Typical routing

Solvent synthesis: TR-8 as standalone sequencer without external clock
• Set TR-8 Tempo to ~ 120 BPM
• Layer patterns over Part Select buttons
• Audio OUT → Monitor / Mixer IN
• Alternatively: MIDI OUT → DAW (Ableton Live) for synchronization
Sync with modular setup: TR-8 as master clock for Volca or Eurorack
• Korg SQ-64 SYNC OUT (3.5 mm TS) → TR-8 SYNC IN
• TR-8 SYNC OUT → Volca Kick / Bass SYNC IN
• All devices synchronize to SQ-64 pace
Multitrack recording: Uploading individual tracks to DAW
• TR-8 Main OUT L / R → MOTU 896 IN 1-2 (left / right drums mix)
• Alternatively: Assign OUT A → MOTU IN 3 (bass drum), Assign OUT B → MOTU IN 4 (HH / files)
• In Ableton Live: record into separate tracks
• Clock: Midi from Ableton → TR-8 Midi IN (Clock CC 248)

Connection instructions: The examples below show typical signal flows in practice. For specific details (jitter, buffering), see section above.

Note

SYSEX export / import via MIDI. In Ableton Live: MIDI tools pod for synchronization of bank selection.

Notes / service / modifications

Manual available: MANUALS / Roland-tr- 8-manual.pdf
Compatible with the KORG level of synchronisation devices (Volca, SQ-64) via Sync IN / OUT
I recommend archiving SYSEX banks after every session you like
When problems with Sync IN / OUT: check cable (3.5mm TS, not TRS!)
