"Another interesting experiment with only original live created MS-20 / MS-50 sounds (incl. beat), no FX at all!

The SQ-10 triggers and sequences all synths:
- The MS-50 plays a rythmic bass pattern (SQ-10 channel A+B).
- The MS-20 plays another rythmic pattern using 2 different tuned VCO's, also sequenced by channel A+B, but using the inverted signal, which also goes through the MS-50 integrator for portamento purposes. EG1 controls the VCO frequency and swaps between 2 CV values every 32(!) steps, by using step 1 trigger output (which triggers once every 8 steps) divided by 4 (MS-50 divider) to generate a trigger once every 32 steps.
- The other MS-20 plays a simple beat, a bass drum with hi-hat pattern (channel C)."

midi-din sync jam session

"tr727 is master, midi goes to miami, from there din to 909 from there midi to bassline from there din to 606, it all works with no glitch or delay in timing. I chose this "exotic" wiring on purpose to demo the whole "hook up some din sync" thing. Some live programming is hard to do with one hand sorry! at the end you can see the 909 and the miami both in shuffle mode, really great."

Roland TR77 Rhythm Machine

via this auction
"Roland TR77 Rhythm synth.
The Roland Rhythm 77 drum machine was Roland's first product (formerly Ace electronics) - released in 1972. It is actually an updated and relabelled Rhythm Ace FR-8L.

It was one of a trio of drum machines released by Roland that year, offering features intermediate between those of Rhythm 33 (TR-33) and Rhythm 55 (TR-55).

It comes in a flat wooden case with a metal base and has a holding for scorebooks - was dedicated to put at top of an organ for rhythm accompaniment.

General Product Information:
Contents
* 1 Rhythms:
* 2 Instruments:
* 3 Some technical inside:
* 4 External Sync

Rhythms:
· Latin: rhumba, beguine, cha-cha, mambo, samba 1&2, bossa nova, baion, bolero, tango
· Rock: rock'n'roll 1&2, slow rock, ballad, western, march, jazz waltz, waltz, cancel
· 2beat & 4beat: bass drum, snare, fox trot, swing, parade, shuffle

Instruments:
Bass drum, snare drum, lo conga, low bongo, high bongo, rim shot, maracas, high hat, cymbal, tambourine, guiro, cow bell. Rim are used for metronome, too.
has a little mixer for: bass drum, snare drum, guiro, high hats.
has a tempo & volume fader; and a fade-out option : for start there's no button, it's a finger-sensitive touch-bar, supports double tempo.
the power switch is not a primary AC-switch.

Some technical inside:
There's no IC inside - only one VCA...
Left: transformer, rectifier, softstart.
Mid: master clock, 5 dividers, reloop & down-beat LED, diode matrix.
The 1st divider is connected to the tempo-up switsch for a 1:1 or 1:2 ratio, the 2nd ones for switching between the 4/4 and 3/4 clock - 1:2 or 1:3 ratio.
Right: the voice board, mixer & output stage. BD, LC, LB, HB, rim are passive circuits.
Bottom: the rhythm switches...
External Sync
There's a little possibility to use din-sync on this device.
Logic board: leftest transistor, on its right the base resistor, solder on lower pin the clock line. For start/stop - its like a pedal switch - just put a transistor serial into the male connector: gnd=emitter, top=collector, base=start/stop line.

Works best at 8 ppm clock, up-tempo off for best results. On up-tempo on the guiro & tambourine it sounds bad as they have a 2nd trigger input which they get from the 1st divider."
