Palmelund Synthesizers Ampel

via this auction

"Designed to work with the Ciat-Lonbarde family in mind but will work with all sorts of banana synths.

----------

- Banana nodes follow the Ciat Lonbarde color scheme (mostly) warm colors are outputs, and cold colors are inputs, (i consider grey a cold color)

- Outputs are 0-9V

- Output gates can be staked to produce CV. but if a gate output is used in a stack, it might not work with a logic input, luckily there are plenty gate outputs., 8 on each of the first 3 modules!

(The two LFO outputs are lower impedance and isn’t as suited for stacking, but the rest of module 1,2 and 3 outputs are great for stacking)

-Power supply: 12V dc center positive 5.5mm/2.1mm. (same as CL).

The modules (left to right):

1. LFO / DIV: are two clocks (LFOS) with a logic output and a sync input. And a clock divider with an input and a reset.

2. A shift register, upper banana is clock input, lower is data input. Upper button is force input high, lower is force input low.

3. Is a magic sunset scene with sparkling stars.

4.You put 3 gates in, and they will choose one of the 8 pots and output a cv at the warm node, corresponding to that pot.

Patching tips!

The base idea was this:

Clock the logic shift register and sunset with the 2 clocks, obviously there are only 2 clocks, and 5 inputs. So use their own logic outs and cross patch them. Take a random logic and and feed the clock divider with it. Take a division and and input it into one of the sync inputs. If you wait, the device will now fall into a repeating, but often quite chaotic (depends on the patch) rhythm. Choosing a bigger or smaller division, or a logic that fires more often or less often sets the repeating length. Adjusting of the clocks slightly might change the sequence completely, and you might not get it back!.

Take your 3 favorite logic gate signals and patch it to module 4 and send it to something (could even be one of its own inputs) and stack a few of the unused gates and send it to something else."

HOW TO MAKE: Thom Yorke - VOLK sequenced by Ground Control played on Roland JV and GHOST

video upload by Endorphin.es

"If anxiety had a sound, how would it sound like?

This spooky season we are fully enchanted by @Thom Yorke's soundtrack for 'Suspiria' movie (2018) and we decided to to recreate this amazing masterpiece on our rig made using Ground Control as a sequencer, Roland JV1010 as a multi-timbral synth voices and the GHOST as our end of chain master effect processor. With its hypnotic 10 step poly meter sequences and demonic scales, morphing effects and creepy sounds you are guaranteed to have goosebumps!"

After Later Audio CLOVERLEAF: Intellijel Case Interface

video upload by After Later Audio

"Cloverleaf is an interface for the case 1/4" jacks in Intelljel cases. The jacks are marked as if they are part of the case, so the jacks marked out, require an input. I know it's confusing, but my brain just may be a little backwards.

The module sports both input and output for either a consumer line level (0.447Vpk) or a professional line level (1.095Vpk). These levels are controllable via jumper on the back of the module. It can also have a single input and output channel switched to pedal level. The case output is fed to the headphone amp that has a corresponding level control. The module otherwise does not have any level control and relies on using a VCA or other module to perform any level controls.

The module can essentially be run in one of three modes:

1) Stereo line level in and out

2) Stereo line level in and out via the left side and mono pedal in and out on the right side. In this mode the stereo line levels leverage TRS on the 1/4" jacks. You can use the included 3.5mm couplers to get TRS on the 3.5mm side.

3) Mono line level in and out via the left side and mono pedal in and out on the right side.

For Palette 64hp users only have two 1/4" jacks. You can choose if you want to use the case jacks as either inputs, outputs, or one input and one output."

New kNoB technology ARLPG active resonant LPG Eurorack Module

Demo track video upload by kNoB Technology

"ARLPG is an active resonant LPG of the dream
This is just a little music demo, the bass part is based on the sound of the ARLPG
SAW wave from VCO + ARLPG and sidechain in the track.

Active Resonant Low Pass Gate

ARLPG is an active resonant LPG of the dream
This is an active resonant filter 12db\oct based on vactrols.

When creating it, I had a goal to make a compact and powerful tool for filtering signals. First thing - I tried to keep the bouncy sound of great-grandfather in the face 292, the second thing is to add a completely new resonance circuit, also driven by vactrols, in which the resonance would have a large amplitude at medium and low frequencies and decrease towards high frequencies, in order to avoid the frequent case of uneven auditory perception of a high level of resonance.

The REG (regeneration) knob was also added, which gives additional functions, at the minimum value of this knob, the filter does not color the signal, and works like a VCA, as well as reducing the attenuation of vactrols, at intermediate values it reduces low frequencies in the resonance circuit and allows you to finetune both the character of the resonance and the sound of the filter.

The filter has two operating modes HP and LP.
By voltage, you can control the cutoff frequency and resonance.
Like any good LPG, ARLPG is very friendly to gate signal management, since vactrols have their own natural release, which depends on the time and duration of exposure.

Device inputs and outputs
IN - audio signal input in ARLPG
OUT - audio signal output from ARLPG
Freq - CV input for filter cutoff frequency control
Res- CV input for filter resonance contro

DOUBLE- MODULAR AMBIENT [ ZOIA EUROBURO - DECKARD'S VOICE - BATUMI - DISTING MK4 ]

video upload by leonardoworx

"In this patch i made a double sequencer, on the amazing Zoia Euroburo, with probability, ratcheting and polyrythms. The sequenced voices are the Deckard's Voice and the Disting MK4 OSC.
Zoia also sends clock to Xaoc Batumi (that modulate various parameters on both voices) and process audio adding a PingPong Delay and GhostVerb.
So, in a small case, like an 84 hp, thanks to the Zoia Euroburo, you can achieve really complex results (and the effects section is stunning).
Hope you like!"

SynthPlex 22: Shear Relic OB Inspired Poly Is Back!

video upload by sonicstate

It's goes to 11.

"Some time back, we spoke to a young guy: Jacob Brashears (still in college) who was working on an Oberheim inspired analogue poly synth. At the time it was very inspiring and great to see some talent coming up. Then it went quiet. I mean a lot has happened since then right?
Jacob has finished school, now is working on bringing his vision to life. It's also acquired another couple of voices, so probably should be called the Relic 8 now..

Jacob has a pre-production prototype form and it's a lovely looking thing with a lot of really neat (and expensive looking) UI ideas.

Sadly we can't listen to it yet, as the semiconductor shortages have meant that they haven't been able to get it quite ready. The hardware is pretty much done, it's just now the software and auto calibration - which as we know is a non-trivial job in itself.

It's clear that he has been living and breathing this instrument for years and has really immersed himself in it's production. We really hope he can bring it to fruition in the planned timeframe which is going to be March 2023 for a limited production run. With more to come.
The shearelectronics.com website needs updating, but you can still email them if you are interested in this machine at relic at shearelectronics.com."
