Yorick LFE now has a Patch Librarian. Also: marking and moving Favourite Patches on OB-X8.


video upload by Steve Hunt

"The Low Frequency Expander from Yorick Tech now has a patch librarian so you can save blocks of patches from a synth and send them back to the synth in the same or a different location. A great way to organise and back up your patches.

You can also can now mark patches as Favourites, step backwards and forwards through Favourite patches, step through patches in a sound category, and step through just the Favourite patches in a category. It can also fetch the favourite patches from the synth, store them in the LFE as a SysEx file and then send them back to the synth in a block, rather than having them spread around different locations in the synth."

Yorick LFE with Trigon 6


video upload by Steve Hunt

"This is 10 patches I've made to demonstrate some of what the Low Frequency Expander can do with the Sequential Trigon 6. It's just my iPhone recording everything through the air, so sorry about the audio quality. Jamie of GEOsynths is about to make a much better video showing similar things!

The LFE can add three complex LFOs, a 6-stage envelope and step sequencer and is able to send these globally to 76 Destinations on the synth (every useful knob and switch) and polyphonically (per-voice) to Destinations on the synth that can be routed through aftertouch (the 3 Oscillator pitches, filter cutoff, amp level, LFO depth and the two FX mixes) so that's an extra 7 envelope/sequencers and 21 extra LFOs for you to play with.

The LFE can also be set up to use its row of 8 envelope knobs to control any device that responds to midi CCs, so while the LFOs are controlling the synth, you have 8 knobs that can control hidden parameters (great for Page 2 of the OBX8 for example, or to control an FX unit etc.) It can also route aftertouch to only the top (or bottom, first or last) note only, allow you to polychain ANY 2 synths together, and be used as a general-purpose mod-matrix for your synth.

Yorick Tech Ltd is currently making a 10th batch of LFEs for delivery in April-June 2023. About 300 have been sold so far and 15 customers have bought two!"

Low Frequency Expander - Yorick Tech


video upload by GEOSynths

"I reviewed the ow Frequency Expander back in 2019 when it was just a single Prototype for the Sequential OB6.

Original Review - [posted here]

Earlier this Year, Steve from Yorick Tech popped around with a new version with an updated Design to match the aesthetics of the Sequential Prophet 5/10 and with a whole host of updates inside too.

Due to bereavement I wasn't able to edit the video, however I have now put it together, demonstrating a variety of functions, as well as with a few different Synths."

Low Frequency Expander // Increase your synths modulation capabilities


video upload by Starsky Carr

"This can give you 3 complex LFOs, additional envelope, sequencer and arpeggiator plus loads of extra functionality. Well worth a look if you've got a Sequential Prophet or OB-6... or any synth with limited modulation. It can work with anything that accepts MIDI CC.

Yorick Tech Adds Polyphonic Modulations & New Panel Designs with Low Frequency Expander 3.0



"Low Frequency Expander 3.0 by Yorick Tech June 2021 Announcing the Low Frequency Expander 3.0, with all-new front panel designs and a major firmware upgrade including polyphonic modulations using MPE for the P6 and OB-6, available from June 2021. The firmware upgrade is free to all users.

The LFE is a standalone, hardware modulation expander that supports the OB-6 and Prophet 6, Rev 4 Prophets 5 and 10, Moog Voyager, Korg Prologue, Nord Wave 2 and a generic ‘CC- Synth’: any device that can be controlled by midi CC messages. It uses midi to provide 3 complex LFOs and a 6-stage envelope – which can also be configured as a 2 to 16-step modulation sequencer – to add considerably more complexity, movement and playability to these amazing synthesizers. It also acts as a 4-slot modulation matrix, allowing you to route velocity, key, aftertouch, mod wheel, CV in (optional) and others to about 50 destinations in the synth (80 with the Nord!)

Selecting a new patch on the synth makes the LFE automatically recall the same-numbered LFE patch from its memory, so the two have their patches locked together. The LFE will display the synth patch’s name and category for Sequential synths. You can select the next (or previous) patch in the same category, stepping through all the Bass patches for example.

New in 3.0
All new front panel designs which are more attractive and with clearer labelling. MPE Midi Polyphonic Expression. For the OB-6 and Prophet 6, the LFE can send modulations to each of the synth’s voices independently, so it will send polyphonic rather than global modulations. Each of the LFE’s 4 modulators on its front panel now operates 7 modulators ‘under the hood’ (1 global and 1 per voice), so the LFE is actually running 7 independent envelope/sequencers and 21 LFOs. As the LFE also allows MPE to work in Poly Chain mode, giving you 12 voices of MPE and 13 envelope/sequencers and 37 LFOs. There are also MPE Spread settings that allow each of the LFOs run at slightly different frequencies and the envelopes to run with slightly different slope times, allowing ‘vintage’ type variations between voices.

Aux midi channel. The LFE can now split its modulations between two different Midi Channels, so you can for example, send LFO 1 and LFO 3 to channel 1 and LFO2 and the envelope to channel 13. You can also set up the LFE to send a new Bank and Program number on the Aux channel every time the LFE changes patch. This allows you to change the Program of an attached FX unit or second synth, to your own choice of Program number, every time the primary synth changes patches. Arpeggiator. The LFE now has an Arpeggiator, primarily for Prophet 5 / 10 and Voyager users. It has Up, Down, Up-Down, Down-Up, Random and Played-Order modes, 1 to 4 octaves, the usual clock sync multipliers and a Key Hold function. There is also a Gate length control, adjustable up to 200%, for overlapping notes.

OLEDs are available in white, blue, green or yellow. Batch 7 starts shipping this month and prices are held despite the global component supply situation."

Prophet 10 desktop with Low Frequency Expander


video by Steve Hunt

"Just got the P10 today and thought I'd have a play with the LFE's arpeggiator and with sending clock synced LFOs to control filter envelope decay, Poly Mod depth, filter envelope amount and filter envelope attack. Just having a play with what's possible - not trying to be even remotely musical!
The pattern is the arpeggiator in Played Order mode.
The LFE display's left column shows the clock sync division, e.g. 8 is one cycle per 8th note and 2b is one cycle per 2 bars."

Low Frequency Expander's Arpeggiator


video by Steve Hunt

"For the Prophet 5 and 10 and other synths that don't have an Arpeggiator, the LFE now has one. It runs off either its own internal clock or from a midi clock. It has the usual Up, Down, Up-down, random and played-order modes. It also has a Down-up mode, 4 octave repeats and the gate length can go up to 200% of the note length so that adjacent notes overlap.

The synth you hear is an OB-6.

Now taking orders for LFE Batch 7 for delivery in June/July 2021.

Low Frequency Expander using MPE to control OB-6's pitch, sync and filter, changing clock divisions


video by Steve Hunt

"Demo 4 of the LFE using Midi Polyphonic Expression (MPE) to modulate each of the synth's 6 voices independently. This also works for the Prophet 6.
LFO1 square wave controlling pitch of VCO1 and 2 stepping an octave.
LFO2 square wave controlling filter cutoff running at a faster clock multiple.
LFO3 ramp up/tri/ramp down controlling VCO1 frequency, sync making the classic sync sound.
Each LFO is sync'd to the synth's clock and has its own clock divisor so they can make crazy synchronised patterns.
Later I turn on the synth's delay and play with its clock divisor, also sync'd to the same clock.
MPE allows each of these 3 LFOs to run a separate LFO for each of the synth's 6 voices, so that's 3 x 6 = 18 LFOs running together. There's actually an extra set of 3 global LFOs and 7 envelopes that I'm not using in this demo."

Low Frequency Expander using MPE to control OB-6 Part 3: pitch, velocity and aftertouch


video by Steve Hunt

"The Yorick Tech Low Frequency Expander is being used here with MPE (Midi Polyphonic Expression) to control the aftertouch section of the synth, then the pitch bend and then the filter cutoff. MPE allows each of the synth's 6 voices to have its aftertouch, pitch and filter cutoff (or PWM) controlled independently, i.e. POLYPHONICALLY!

The OB6 can assign aftertouch (coming from the LFE via MPE) to the pitch of its VCO(s), loudness, LFO depth, filter cutoff or filter mode. In the first demo here, it is controlling VCO1's frequency, and as the VCOs are synced to VCO2, this gives the characteristic sync sound. The LFE is also multiplying each of its 6 envelopes by velocity, so each voice gets a different amount of sync envelope depending on each note's velocity.

The second part of this demo uses MPE to control the pitch bend of each of the synth's 6 voices. I'm using it here with 6 LFOs to generate vibrato, again multiplied by polyphonic velocity to give vibrato with each note having slightly different vibrato rates and depths controlled by its velocity.

The third part of the demo uses the MPE 'Y-channel' which the synth can assign to filter cutoff or PWM. Here it is being used to control filter cutoff, again with velocity affecting each of the LFE's 6 sawtooth LFOs so that each note can have different LFO depth.

This will all do the same with a Prophet 6.

This is an excerpt of a song of mine called 'Did we do the right thing?'

There's still a lot of work for me to do to be able to release this to LFE customers so this is just a taster of things to come for the LFE!"

OB-6 controlled by POLYPHONIC LFE using MPE part 2: sequencer, spread and PWM


video by Steve Hunt

"This demonstrates the Yorick Tech Low Frequency Expander using MPE to control each of the synth's six voices independently. First using six 16-step sequencers to control each voice's filter cutoff separately. Second showing 6 LFOs controlling the filters but also showing the use of the MPE spread parameter to give each of the LFOs a slightly different frequency. Third, showing 6 LFOs this time modulating the pulse width of the synth's voices, again with and without the spread applied. Incredibly rich PWM from 6 LFOs, each with a different rate."

OB-6 controlled by POLYPHONIC LFE using MPE


video by Steve Hunt

"I'm working on implementing MPE in the Yorick Tech Low Frequency Expander. Normally the LFE's modulations are Global (monophonic), but MPE allows them to be truly polyphonic with 6 independent additional envelopes.

The demo shows the LFE's 6-stage envelopes controlling the OB6's filter cutoff polyphonically. This frees up the synth's ADSR to do something completely different. After a few seconds, I turn up the X-mod so that the synth's ADSR starts controlling VCO1's frequency. The OB6 now has three independent polyphonic envelope generators!

There's still a lot of work for me to do to be able to release this to LFE customers so this is just a taster of things to come for the LFE! Three Polyphonic LFOs next..."

"Design matched Sequential OB-6, but works for Prophet 6 and can be used for other MIDI synths too.

Display works perfectly but was hard to photograph without looking weird. It looks the way it should in person."

Low Frequency Expander providing Top Note Aftertouch for OB6


Steve Hunt

"My Yorick Tech LFE is out of shot. Notice how ONLY the highest note I play is getting vibrato from aftertouch! It's taking normal channel aftertouch from the OB6, working out which is the highest note I'm playing and then sends aftertouch back to the OB6, but only on the highest note. It can also send for the lowest, first or latest notes instead. Most of the benefits of a poly aftertouch keyboard but using a standard synth with mono (channel) aftertouch.

Sorry about the shaky camera!

Prophet 10 using Low Frequency Expander (Yorick Tech LFE) for Release Aftertouch (RAT)


Steve Hunt

"The LFE captures the after touch value just before the last key is released and uses this to control any parameter on the synth (or midi CC-enabled effects). It can be used a lot like Release Velocity to affect things after the key has been released, often Release times, FX depths etc. Here, an LFE customer is using RAT to bring in extra filter modulation after the note has been released, but only when he gives the note a quick push before letting go."

Low Frequency Expander 2.0 by Yorick Tech



"Announcing the Low Frequency Expander 2.0, a major firmware upgrade, free to all users, available from December 2020.

The LFE is a standalone, hardware modulation expander that supports the OB-6 and Prophet 6, Korg Prologue, Nord Wave 2 and a generic ‘CC-Synth’: any midi device that can be controlled by midi CC messages.

Simply selecting a new patch on the synth makes the LFE automatically recall the same- numbered LFE patch from its memory, so the two have their patches locked together. You can select the next (or previous) patch in the same category, stepping through all of the Bass patches for example.

New in 2.0
Support for the Rev 4 Prophets 5 and 10, and Moog Voyager. CC-Synth and any two synths are included free; others are extra cost.

Internal midi clock for controlling the LFE and external devices.

The synth’s patch names can now be read and displayed by the LFE, so if you edit patches using for example Sound Tower, the LFE can get these directly form the synth even though the synth itself can’t display them.

Release Aftertouch (RAT) allows you to fix an aftertouch value just before releasing the last note and hold that value until the next note is played. This can be used in a similar way to release velocity, which is sadly only generated by a few keyboards. RAT lets you, for example, increase Release times or increase FX depth just by giving the keys a quick press before releasing them.
The LFE now supports Poly Chaining using any keyboard as master and any synth as slave. The LFE handles all of the note sharing so the attached keyboards simply remain in their normal mode.

You can limit the number of voices played, add a second Sub Voice like a sub oscillator but at any pitch, and can add a velocity offset to the sub voice, so that for example, a second voice a 5th higher comes in only when played with more velocity."

The Beast Synthesizer from Yorick Tech


Steve Hunt

"I own Yorick Tech Ltd, maker of the Low Frequency Expander (LFE) for OB-6 and Prophet 6. [see here] This is a prototype / test bed for a mono synth project which will be a cut-down version of this, using the best bits. Possible poly version too....

Mostly my own design, including clones or designs inspired by various vintage synths, including 3 Oakley filters.

2 x CEM 3340 VCOs, one with supersaw and one with double-wavefolder. Each has its own PWM LFO and pitch ADSR and sub oscillator.

LFO3 is from the LFE and contains a hidden LFO, sampling the main LFO but with clever synchronisation so that patterns repeat in a musical way.

Ring modulator.

6 ADSRs (2 miniMoog clones, 2 digital and 2 CEM) and 7 LFOs, many VCAs including 2 mixers and stereo panning for each mixer.

4 filters:
Oberheim SEM doubled to give 12 or 24dB slope.
Roland SH-1 based filter, again with 12 or 24dB.
904a Moog Modular clone
miniKorg Traveller-based design

Filters can be set in series, parallel and are fed from the 2 mixers as 2 pairs.

Spring reverb.

4x5 mod matrix.

Midi or CV in"

Yorick Tech Low Frequency Expander modulating the Nord Wave 2


Published on May 18, 2020 Steve Hunt

"The LFE was designed to control the OB6 and Prophet 6 synths but is now able to control the Nord Wave 2 and Korg Prologue as well. Just a quick demo to show some of the modulation possibilities available - there are about 80 modulation destinations which can be controlled by 4 generators: a 6-stage envelope that can also be a 16 step modulation sequencer, and 3 complex LFOs. Each can also be multiplied by another controller, so the level of each modulator can be affected by aftertouch, velocity, mod wheel, one of the other modulators etc..."

Korg Prologue controlled by Low Frequency Expander for extra modulations


Published on Mar 18, 2020 Steve Hunt

"The Yorick Tech Low Frequency Expander (LFE) is designed primarily for the Sequential / DSI OB-6 and Prophet 6 synthesizers, but it can now also control the Korg Prologue - another synth with relatively few modulation sources. The LFE adds 3 complex LFOs and a complex 6-stage envelope generator which can also be used as a 2 to 16 step sequencer. This is a simple demo of what the LFE can add to a few of the Prologue's factory patches. Not trying to be remotely musical here, just showing some of the extra modulation abilities on offer.

1. Runner Brass. Two slow LFOs modulating VCO1 and VCO2 shapes giving a very rich sound, envelope modulating filter resonance so each note starts without resonance, another (fast) LFO modulating filter frequency but only brought in with increasing velocity.

2. June Pad. Chorus speed controlled with envelope so it speeds up through the note then slows down. Reverb off during note but then full depth after note released.

3. In my dream. Velocity and LFE's envelope modulating Xmod depth, velocity modulating timbre balance reducing the level of the 'tinkle' with more velocity. LFO 3 comes in after about 2 seconds with a repeating pattern modulating the filter frequency, then I change the pattern type.

4. Solid Bass. Complex envelope modulating filter freq , LFO1 modulating VCO1 shape to give more richness, LFO2 is a key-triggered saw wave modulating Osc3 shape which gives a dark beat, LFO3 does the same with resonance giving a ching-ching beat with increasing velocity.

5. Opal mine. 7-step sequencer controlling filter frequency, filter freq and res controlled by LFO 2 and 3 giving the flutter effect, velocity controlling the Korg's LFO rate.

6. ReeseFlux. Envelope controlling the Korg's LFO rate and the depth of LFO1's sine wave which is modulating filter drive. LFOs 2 and 3 are modulating resonance and filter freq which come in after a few seconds.

8. Sherbet. Longer sequence modulating filter freq, LFO2 modulating Osc3 shape with velocity, LFO3 modulating filter res.

9. Raid rush. Envelope modulating filter env depth, velocity controlling the Korg's amp envelope's Attack time, LFO 2 modulating Osc3 level with a saw wave, LFO3 controlling filter freq.

10. Sparkle. Envelope controlling Osc 3 shape, 3 LFOs coming in after a del and/or fade to modulate filter frequency and VCO1 shape.

11. Poly spread. Complex envelope controlling filter freq and 3 LFOs coming in after delays to modulate 2 VCO shapes and filter env depth, one with just 3 cycles.

14. Cinematica. Envelope controlling Osc3 shape, filter freq controlled by a delayed stepped wave from LFO1, LFO2 modulating resonance, LFO3 brought in by velocity to affect VCO2 Octave giving the repeating beat pattern."
