RSF Kobol Expander with CV control of waveform, decay and sync amount #rsfkobol #analogiapl


video upload by analogia pl

"This is one application of patch panel CV inputs in a Kobol Expander (which is not for sale, by the way). I’m sending a CV/gate pair to deliver note info but also a second CV (playing notes) that goes to an attenuator and then a multiple.

So, effectively, that second CV changes waveform of oscillator 1, decay of VCA envelope (that’s also routed to VCF) and amount of sync."

PlantsSystem-CHRONOS v1.0.0

"CHRONOS – a tiny granular synth built on a Raspberry Pi Pico2

CHRONOS is a DIY granular synthesizer running on a Raspberry Pi Pico 2(RP2350), with a Waveshare Pico-Audio DAC and a 1.3" Pico-LCD. It layers long, overlapping grains (roughly 0.7 to 3 seconds each) into slow, soft, ambient textures.

Features:

Grains are drawn from four waveforms: Sine, Triangle, Soft Saw and Bell

Four selectable scales: Hirajoshi, Miyako-bushi, Ryukyu and a Maj7 progression, with the chord changing automatically

Stereo ping-pong delay with feedback

Auto-pan that lets each grain drift across the stereo field

5-step tone control (low-pass), plus a Freeze function that sustains the current grains

The LCD shows every grain live: height is pitch, horizontal position is stereo placement, and size/brightness follows each grain's envelope"

X1L3 - ALLEYKAT - CLOSER 🥔🍆🍑 - 8580 SID - nine inch nails cover - eurorack module


video upload by X1L3

"Potato remake of closer by nine inch nails on the Alleykat module running an 8580 SID chip.

For the five people in the world who want to hear a potato version of the downward spiral in it's entirety, like piggy, consider it a teaser for the full thing. I thought how well this turned out worthy of it's own upload. God tier sexy interpretation of an already sexy bass line, some phatt for the masses filter action and so much voice multiplexing and element hopping that it ends up sounding like there's way more going on than three voices. Pretty happy with the outcome of this. I'd give it an A+ or an S in a 1986 teenager with C64 running and telly cranked to full volume kind of way :)

I suppose when the whole thing is done it'll make a decent demo of what the module is capable of when i get around to releasing it."

Farfisa Polychrome – A short demonstration


video upload by melodikakofoniko

"Farfisa Polychrome – A short demonstration (with added reverb).

My rarest (and most awesome) synth must be the Farfisa Polychrome. It's a thoroughly beautiful Italian string machine from the late 1970s with four independent sections, a BBD chorus, and a great phaser effect. It's kind of similar to the ARP Quadra (but without a mono section—everything here is purely divide-down based). It's similar in size to the Korg Trident or Elka Synthex (HUGE!) but even heavier! It's got a really otherworldly analog vocal chorus section that sounds unique and beautiful, especially when combined with the other sections.

The keybed has a really nice mechanical aftertouch mechanism, similar in construction to the one found in the Yamaha CS series (though this one works with a magnet and a Hall sensor). My Farfisa collection also includes the Soundmaker and the Synthorchestra—Farfisa's earlier but similarly unique and cool machines with a distinctive 1970s sound (compared to the Polychrome, which sounds quite different)."

Moog Micromoog & Modular w/ AJH/MiniMod, Hermod+ analog synth jam


video upload by DreamsOfWires

"Testing my faulty Micromoog with some helpful modules from AJH Synth: My poor old Moog isn't scaling/tracking correctly, so the V-Scale module is being used to modify the 1V/Oct output of the sequencer to produce the correct notes. Video guide to how this was achieved: • Correcting Vintage Synths with V-SCALE - T... [below]

Normally the Micromoog follows a 0.95V/Oct voltage to pitch scale, but mine can no longer even be calibrated to this with it's internal trimmers, so until it can be serviced (probably with some new components), the V-Scale at least makes it useable with external controllers and sequencers.

Sequenced by the Squarp Hermod+, the synth's faulty tracking is then corrected using AJH Synth's V-Scale module, gates coverted by the AMSynths AM997 Gate to S-Trig converter.

Micromoog filter modulated by AJH Tap Tempo VC-LFO, random gate skip by AJH CHance Delay.

Drone is 3 AJH MiniMod VCOs into Matrix VCF.

Mixed in the Cosmotronic Cosmix Pro, reverb from FX Aid, delay from 2HP DLY, final mix recorded on the Disting Mk4."

Correcting Vintage Synths with V-SCALE - Tackling Tracking & Tuning Problems #ajhsynth

video upload by AJH Synth Official

"Using V-SCALE to compensate for the tuning/tracking problems on one of my Vintage Synthesizers, this time a Moog Micromoog from the late 70's. Also, showing how PRECISION VOLTAGES can also be helpful, and bringing the TAP TEMPO VC-LFO, CHANCE DELAY, and the MATRIX VCF into a short performance demo - FULL performance video by ‪@DreamsOfWires‬ can be found here: • Moog Micromoog & Modular w/ AJH/MiniMod, H... [above]

V-SCALE at its simplest will function as a highly accurate buffered multiple, but four of its five outputs are adjustable by way of multi-turn trimmers. These allow for very gradual adjustments to outgoing CV signals, so that they can be made viable for synths or VCOs that are not scaling properly.

Here I'm adjusting/modifying a 1V/Oct signal from a sequencer so that it controls my old Micromoog correctly, but it could also be used with incoming signals other than 1V/Oct, or even to correct am incoming signal which itself isn't scaling correctly or as desired. Each trimmer has an adjustment range of +/- 5%.

My Micromoog's tracking is so far off that it cannot even be corrected using the internal trimmers on the synth, so I'm using the Keyboard Output (KBD) as the CV input, instead. of the intended OSC input. This method bypasses the keyboard, so the keyboard voltage isn't added to incoming control voltages, and so doesn't interfere with it. The only drawback is that the root key will have to be changed to match the notes on a keyboard. That's where the PRECISION VOLTAGES comes in - it can accurately offset an incoming control voltage by semitones and octaves, either up or down."
