T-420 Eurorack Video Synthesizer Module - LoFi Future Glitch Effects Processor

video upload by LoFiFuture

"Available to order:

During packing / shipping of the first batch of these modules, it dawned on me, I haven't made a demo video for it yet!

The T-420 video processor finally gets its Eurorack transformation! Coming in at 4HP and just 23mm deep it is compact to fit into even the shallowest of skiffs.

The three knobs work in conjunction with each other so many effects are possible ranging from frame tearing glitches to bright rainbow colourize effects as well as invert/negative effects. Check out the demo video / pictures for some examples.

Great for processing clean composite signals to add some, or a lot of glitch and grit. It does wonderful stuff in feedback loops too!

This unit works and looks its absolute best when plugged directly into a CRT TV, but it will work with LCD TVs & Projectors and only tends to drop out (lose signal) when the first knob is near its maximum setting. Also works well in bigger video rigs with video mixers/ TBCs etc.

NTSC/PAL Compatible
Weight - 90 Grams
Dimensions - 4HP / 23mm Deep
Power - Uses 12V rail / 210mA max power consumption"

Messing about with the Sequential Prophet 5 rev 4

video upload by Synth-o-rama

"Trying out different patches I made. The Sequential Prophet 5 rev 4 is going through an old Roland mixer, and a stereo spring reverb as well.

Sorry for the video quality. Turns out the iPhone blurs the video whenever it gets sound pressure (from my speakers). I'll might make a better quality video later. :-)"

Studio Electronics BoomStar 8106 Jam - Jupiter/Juno Filter

video upload by Aperture Sound Lab

"A solid Jam with a simple arp-y melody. Boomstar is (by a mile) the best monosynth I've ever played. So good in fact that I ended up handing off the Matrixbrute just to afford one. The unit you see here in this video is the one Voltage&Co was kind enough to lend me. I've got my own 8106 boomstar with slightly darker wood that'll be a mainstay here for quite sometime. This jam is just a short example of what it can do. More of these to come..."

Original ARP 2600 synthesizer, with Antonus Step Brother sequencer

video upload by Synth-o-rama

"This is a POV video, with me exploring my recently purchased Arp 2600 synthesizer. It's an original grey face model from 1976.

Arp potted the modules in this model, to make it more difficult to know what's going on inside them. Especially the 'Moog' filter they probably wanted to keep secret. However, in 1976, with the introduction of the "Halloween" coloured version of the Arp 2600, they no longer potted the modules.

At the same time they introduced their own version of the filter module (they kinda had to, as they got sued by Moog), the 4072. Many people think that it was inferior sounding to the 4012 "Moog" equivalent.

However, although my Arp 2600 is from 1976, and maybe "should" have been equipped either with the potted 4012 Moog filter, or, the unpotted inferior sounding 4072 filter, I was lucky enough to get an unpotted 4012 Moog filter. All other modules in this Arp 2600 are not potted as well. Sometimes you luck out. 🎉"

Ratcheting Effects with the TAP TEMPO VC-LFO Eurorack Module and a Step-Sequencer

video upload by AJH Synth Official

"This Patch of The Week shows a way of achieving racheting effects in sequences using the Tap Tempo VC-LFO - the new voltage-controlled low-frequency oscillator from AJH Synth. It involves using one row of 8 steps to control the pitch of the sequence, whilst a second row controls the LFO, determining the multiplication of the clock speed, which is set by the sequencer's gate output. This LFO then controls both filter and VCA like a repeating envelope generator, and it's clock speed is tied to that of the sequencer. The TAP TEMPO VC-LFO is a very powerful 16-waveform LFO module. Here only a simple sawtooth wave shape is used, but it contains many unusual and complex waves that are suitable for a huge range of applications, 15 of which can be twisted, modifying their wave shape in a similar way to square wave pulse width modulation. Two of the waves are similar to sample & hold, where random voltages are generated. All waves share the same clock behaviour and can be synced to external CV, which makes the module great for use with sequencers. A built-in VCA with level control, along with both bipolar (LFO type) and unipolar (envelope type) outputs."

"Thanks for watching!
Made this interesting patch on the Blue Marvin 2600 by Behringer, and with some help from 2 eurorack sequencers: 2 Qu-Bit Blooms 😁.
The audio is just stereo out from Blue Marvin directly. Some reverb and delay in Ableton, and the UAD Pultec EQ as well as the Studer A8000 tape machine on the Master.

Yamaha CX5M II 128 1985 Black FM Computer with Extras

via this auction

Pic of the 4-Op FM synth engine editor screenshot below.

"This computer has been tested and serviced. It is perfect working order. Comes with many peripherals:
-YK-20 Full sized keyboard w/ music stand
-FM Voicing Program II mini cartridge (installed)
-RX editor cartridge
-Memory cartridge, with new battery (has no case but functions fine)
-FM Music Composer
-FMVoicing program 1
-MIDI recorder
-FM voicing program II full size cartridge
-monitor cable
-printer cable
-rca cable for video
-cassette interface cable
-manual for voicing program 1

Features are better than the original CX5M. It can accept any midi input with velocity. Data can be easily saved to cartridge.

To use cartridge you type in a command. I’ve figure out a few

call music
Opens internal music program

call fmv
Opens FM voicing programs, also the mini cartridge when nothing is plugged in the large cartridge slots

call rx
Opens RX drum machine editor (works with RX11 and RX15)

Also the memory cartridge must be put in the slot with the battery facing towards the keyboard"

"See photos and video. Like New - I would call this Mint. If you're interested, message me 1st and make sure it qualifies as your definition of Mint. It's sold ASIS with Video and Photos. It's a delicate beauty - probably the sexiest boombox ever made. It will be respectfully wrapped for a safe delivery.

Accessories: (unknown if OEM - but I've had them all paired with this unit for over 20 years - so...)
• Microphone - For the Mixing Mic Input on the unit. Works great! But, there is wire stress and cut out unless bend a certain way - you know what I'm talking about - it's in the photos as a close up.

• Headphones - The 1/8 to 1/4 adapter on these is RadioShack.
• Maxell UR Cassette Tape - Not used except for the demo and maybe a bit from other testing.
• AC Cord
• Speaker Jumper Cables Left and Right"

Resonant filters on 80s Akai samplers | How to do it

video upload by Espen Kraft

"The early S-samplers from Akai did not have resonant filters, but by hooking them up to Akai synths at the time you could still achieve it. The individual voices from the sampler goes out a special connector at the back called "Voice out". All the 80s Akai samplers features this connector. With the appropriate cable you took the output here and connected it to the "Sampler In" on one of the Akai synths of the time.
The Akai AX60, AX73, VX90 and VX600 has these "Sampler In" ports at the back. The AX80 does not, just so you're aware. The AX80 was Akai's first synth and it preceded their first sampler, the S612 and is in many ways the odd one in their catalogue."

#OutdoorLiven Jam - SONICWARE Liven 8Bit Warps, Bass & Beats

video upload by ChrisLody

"In this jam I've plonked myself down in front of our veg patch with my trusty DIY 'Synth Tray' (patent pending) with a Liven 8Bit Warps and a Liven Bass & Beats. This is a combination I've been meaning to try for a while and they compliment each other really well with the Bass & Beats filling in for the 8Bit Warps lack of 'normal' drum sounds and the 8BW able to play chords where the B&B can't.

I'm running the B&B into the 8BW's Line In so there is no need for an external mixer. Recording is taken care of by my aging Korg Sound on Sound."
