Donner L1 Synthesizer Inside and Mods


video upload by Maffez Synthmods

"Some easy modifications (Filter FM, VCA boost) and a couple of inside pictures of the Donner L1 synthesizer module. You can see how the alfa par ICs are used for VCO, VCF and VCA, how the whole magnetic keyboard system is arranged and how the ADSRs are digital (not that they soudn any less funky!). All sounds in the demo are from a modified unit."

Polyend Pedals // MESS Step and Press


video upload by Starsky Carr

"Some things ooze quality ... welcome to the Polyend MESS, Step and Press guitar pedals. But just like my MoogerFoogers I'm not going to be stomping on them any time soon!

The MESS is a Multi Effect Step Sequencer with 4 tracks containing one of 74 on-board FX and sequenced in 16 steps.

The Step is a beats machine. Filled with 50 kits and 2000 samples and room for 1000 songs. With per step parameter setting and onboard FX, limiter and saturation it's much more than a simple drum machine.

Press is an ANALOG stereo VCA compressor (everything else I've used from Polyend has been digital), with a sidechain input, LP and HP for the sidechain plus a dry/wet mix knob and a tilt EQ. A super little desktop/stompbox compressor."

30:21 In a Nutshell...

CS80 inspired VCF


video upload by Cornel Hecht

"Both filters (HPF and LPF) feature adjustable resonance, which boosts the sound at the cutoff frequency. This gives the CS-80 its distinctive "singing" character, especially for string and brass sounds."

PicoCore PO-33


video upload by SynthCone

"Эксперементирую с альтернативной прошивкой PO-33.
Очень интересный грувбокс. Можно делать ритмы, мелодии. Имеет 16ти шаговый секвенсор.
8 дорожек.
Можно настраивать тональность каждого шага. Отдельно менять скорость и громкость каждой дорожки.
Можно загружать свои семплы.
С остальными возможностями пока не разобрался. Больше крутил на абум и вроде прикольно получилось👍

Эту версию PicoCore вы можете спаять самостоятельно, на предстоящем мастерклассе.

Googlish:

"Experimenting with alternative firmware PO-33.
Very interesting groovebox. Can make rhythms, melodies. Has a 16-step sequencer.
8 tracks.
You can adjust the tonality of each step. Separately change the speed and volume of each track.
You can load your own samples.
I haven't figured out the rest of the options yet. I mostly played around with it and it seems cool 👍
