Typical routing

Standaloneuses: CA- 30 as a solo performer
• Choose Style (e.g. Bossa Nova)
• Play note on mini keyboard
• The Arranger automatically generates bassline, harmony, rhythm section
• Output → PA / Monitor
MIDI sequence sync: CA30 synchronized with external sequencer
• Korg SQ-64 MIDI OUT Clock → CA30 MIDI IN
• SQ-64 sets the pace and the CA-30 is automatically synchronized
• CA-30 plays bass and chords by Style
• SQ-64 controls other synthesizers (Volca, Behringer Crave)
Hybrid arrangement: CA30 as a hybrid sequencer + live key
• Ableton Live plays drums a synth bass
• CA30 MIDI IN Receive clock from Ableton (Sync mode)
• CA30 adds harmony and live interaction
• All audio → MOTU 896 for recording

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

Note

Presets are immutable (production). Sesion sequences can be recorded, but they are lost by switching off without external power (without internal battery backup).

Notes / service / modifications

IMPORTANT: CA30 is ARRANGER with its own sounds - NOT EMU / EXPANDER (unlike MT32 / CM32 / CM64)
CA- 30 Style Player: Software in APP _ DATA / for PC style management (legacy)
Music Styles Card Slot: Compatible with RA50 Series E20 Cards (Music Styles)
Sequence: Sesion sequences can be exported to PC (MIDI export functionality)
MIDI Control: MT32, CM32, CM64 expanders via MIDI OUT
The inventory contains only a unit without keyboard; an original power supply is available
Attention: RCA outputs are low-level (-10 dBV) - linear marker before mixer recommended
Interoperability: MIDI Clock IN compatible with any sequencer (SQ-64, DAW,...)
31 buttons + 11 indicators = professional control panel
