Frequently Asked Questions - CM-64 ROLAND

What is the maximum polyphony of the Roland CM-64?

The Roland CM-64 features 32 voice polyphony using LA synthesis and PCM samples.

How do I change the assign mode on the CM-64?

You can change the assign mode via MIDI System Exclusive messages. The parameter Assign Mode (address 00 05) supports values 0–3 corresponding to Poly 1, Poly 2, Poly 3, and Poly 4.

Can I use the CM-64 as a general MIDI sound module?

Yes, the CM-64 responds to MIDI notes, program changes, control changes, and pitch bend. However, it does not implement General MIDI standard; it uses its own sound map.

How many parts can I layer on the CM-64?

The CM-64 supports up to 6 independent parts (Part 1–6), each with its own volume, reverb switch, and sound assignment.

What types of reverb does the CM-64 have?

It includes a reverb effect that can be switched on/off per part, with adjustable reverb level via MIDI or front panel (if available).

How do I reset the CM-64 to factory defaults?

Perform a System Exclusive Reset by sending the appropriate SysEx command (address 7F xx xx) or by power cycling while holding specific buttons (detailed in the manual).

What is the difference between Poly 1 and Poly 4 assign modes?

Poly 1 groups all notes on one channel, Poly 2 splits into two groups, Poly 3 into three, and Poly 4 into four independent zones.

Can I use the CM-64 with a computer?

Yes, via a MIDI interface. The CM-64 communicates using standard MIDI DIN connectors (IN/OUT).

What is the pitch bend range of the CM-64?

The pitch bend range is adjustable from 0 to 24 semitones (2 octaves) via MIDI parameter Bender Range.

How do I set the output level for each part?

Use Part Volume controlled via MIDI Control Change (e.g., CC 7) or System Exclusive parameter OUTPUT LEVEL (address 00 08) for global output.
