Spark - A Portable Open-Source Synth (based on ESP-32 and AMY)


video upload by povle

"Meet Spark - a portable open-source synth running the AMY synth engine."

00:00 DX7
01:11 Sampler
02:09 Juno-106
03:23 BLE MIDI

https://github.com/povle/spark-synth


"Really wanted something OP-1 sized but more performance focused (and cheaper), so i made it myself. It runs on AMY, i've currently added the built-in patches and implemented a BLE MIDI keyboard mode, later will start adding my own instruments.

Originally planned to use korg nanokey2 as the keybed, but the feel was so bad that i had to switch to low-profile mechanical key switches.

Overall extremely happy with the result, especially given that it's my first big electronics project"

Modified Univox Mini-Korg For Sale

via Tonetweakers

"Univox Mini-Korg Synthesizer 700 For Sale. This Minikorg has been meticulously refurbished by perfectionists and is in perfect working order and ready to play.

This unit has some very useful modifications that expand its capabilities.

Adjustable Resonance
The stock minikorg just has a single switch for resonance boost, but this one's got 2 additional rotary pots added for variable resonance of the high pass and low pass filters - it really lets this minikorg scream! This mod alone is a huge improvement over a standard minikorg.

Filter Input
There's also an audio input allowing one to process external sounds through its filters.

Adjustable Chorus Rate
There's a pot to adjust the rate of chorus 1.

Octave and Waveform Mixing
These mods give you the ability to mix waveforms and octave divisions, resulting in a fatter sound. These mods are a bit strange and interact with the octave and waveform switches, so they take a little getting used to.

These additional octave and waveform pots are active at the very top of their range and are more like switches and are sometimes inactive, depending on your settings. Sometimes octave switch settings will cause a drop in volume if the appropriate knobs are not adjusted, and sometimes there will be a change in timbre of the selected waveforms if the knobs are not adjusted properly. It's a bit confusing at first. We can probably remove these mods for you if you'd like so the octave and waveform switches work as they normally would in a stock unit, but this will remove the ability to mix waveforms and octave divisions - please email us to discuss if you'd like these mods removed (we would just remove the wires connecting the mods, not the additional pots).

These mods give this minikorg more sonic possibilities than a stock unit and add value to this example.

We paid our tech for 5 hours of skilled labor to get this unit working great again. In addition to fixing any problems, he did the following servicing:

Cleaned jacks
Replaced all power supply electrolytic capacitors (he says someone previously replaced the other electrolytic capacitors)
Replaced fuse
Cleaned and lubed all pots
Calibrated VCO"

"Here's a sweet Roland Jupiter 6 legendary analog polysynth.. and in Mono mode, one of the best bass / lead synths ever made... I much preferred it over my Voyager XL, Odyssey and Minimoog D : )

It is in great condition in and out. ALL keys, jacks, sliders, buttons, voices, filters work as they should. This Jupiter was serviced by fully early last year. It was all detailed, calibrated, checked, and it was upgraded with the Tauntek Firmware Update.. check out the specs online.. it really adds so many cool things to the J6. ALSO comes with custom dust cover : )

CHECK OUT the quick video posted on this ad of THIS JUPITER 6!"
