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."

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.

Very interesting groovebox. Can make rhythms, melodies. Has a 16-step sequencer.

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 👍
You can solder this version of PicoCore yourself at the upcoming master class.

TOMITA, CASIO & THE COSMO SYSTEM

Don't miss the links further below.
"TOMITA, CASIO & THE COSMO SYSTEM: Casio collaborated with Casio way back in the early 1980’s to create the COSMO synthesizer which was a huge rack of custom devices and computer system that ultimately became the CZ-101 Synthesizer and FZ-1 Sampler…the first 16bit sampler. From what understand the CZ-101 has in its code something like 64 different waveforms of which only 8 were selected for the CZ. I’ve seen someone post about this and was trying to make them accessible. Phase Distortion synthesis is the “real” FM (again as I’ve read somewhere) and Yamaha’s FM is different though I’m not sure what those differences are. The CZ started my career as a sound designer and remains one of my Top 3 instruments though I use the Virtual CZ soft synth by Oli Larkin. I have my entire collection of sounds from all the way back to 1986 and all the ones used on my “Lost Childhood” albums that were done with just two CZ-1’s run from a Roland MC-500 MIDI sequencer in real time through a Roland R880 digital reverb direct to DAT. A fantastic and classic synth! 🎛️ 👽"
