Korg Poly 61 | 1980s Synthesizer

video by Pure Ambient Drone

"The KORG Poly-61 is an analogue programmable polyphonic synthesizer released by Korg in 1982, as a successor to the Polysix. It was notable for being Korg's first largely 'knobless' synthesizer - featuring a push-button interface for programming, dispensing with the Polysix's knobs and switches. Wikipedia

The 1980s synthesizers were a thing unto themselves and Korg really did a great job on the Poly 61 synth. Its got a lot of character going for it and nice fast envelopes too! This is the Korg Poly 61M that I am sound demoing here."

DIY reclaimed wood "eurorack" synthesizer case

video by Extralife

"In this video I built a super-simple all-wood eurorack synth case using only hand tools and reclaimed materials like pallet wood. I think it came out pretty well but the dimensions could've been improved - I will post updated plans shortly."

1978 MTI 16R Auto-Orchestra

"MTI 16R Auto Orchestra drum machine w foot pedal and foot keyboard. This item has been thoroughly cleaned and tested. Full set of rhythms, settings, expansion card, killer bass & filter and accompaniment voices work great, intermittent clicks with tom sounds, however. Improved with contact cleaning but still occasional. The LED cursor flashes with tempo, but number wavers and does not reflect bpm (I believe this applies to both model MTIs). Foot Keyboard works perfectly. Foot pedal in poor condition, will start/stop rhythms and diminish chords only. All outputs work correctly. This unit has been racked in an enclosed cabinet, free from dust, etc. Solid life left in this rare drum machine!"

"Very Good condition. Only some light scuffs to wood sides. Recently professionally serviced, including fully replacing all electrolytic capacitors with audio-grade Nichons, some repairs to the voice circuit on the mother PCB, general cleaning of board & jacks, and a full tuning/factory calibration. Works excellently, sounds incredible. Roland's first polyphonic analog synthesizer, featuring a very early digital memory system, allowing this vintage synth to save presets!"

Low Frequency Expander's Arpeggiator

video by Steve Hunt

"For the Prophet 5 and 10 and other synths that don't have an Arpeggiator, the LFE now has one. It runs off either its own internal clock or from a midi clock. It has the usual Up, Down, Up-down, random and played-order modes. It also has a Down-up mode, 4 octave repeats and the gate length can go up to 200% of the note length so that adjacent notes overlap.

The synth you hear is an OB-6.

Now taking orders for LFE Batch 7 for delivery in June/July 2021.

SM Pro V-MACHINE running BlueARP and retro-review

video by graywolf2004ru

9:32 on reminded me of Depeche Mode's See You. Different sequence of course, just similar vibe.

"This is still a cool piece of hardware, despite of its limited power. I wish they make a more powerful version some day.
When I first used V-Machine 10 years ago - I tried to run BlueARP inside it and it worked after a few tweaks to the code. I didn't post it back then, so now I decided to revive that experiment.
To do this in 2021, I had to bring back Windows XP compatibility for 32-bit version of BlueARP (it was quite a challenge) but finally it works!
I don't think it has lots of practical usage in 2021, but still V-MACHINE is a cool artifact of its time and running BlueARP + Synth1 inside it makes it even cooler.
