Roland CM-32P

From Wikipedia, the free encyclopedia

The Roland CM-32P is a MIDI synthesizer module first released by Roland Corporation in 1989. Its appearance is identical to the CM-32L with the exception of a PCM card slot at the front. The front included a volume knob, a power switch and two leds indicating power and MIDI data. On the rear panel there are three MIDI connectors (IN, OUT and THRU), a balanced 1/4" jack connector for headphones and two unbalanced 1/4" jack connectors for a mono/stereo output (-10 dBu).

The synthesis used is PCM (Pulse Code Modulation) which allowed for more realistic sound reproduction of musical instruments than the LA (Linear Arithmetic) synthesis. The sounds included are partly of the same origins as the professional U-110, U-220 modules and the U-20 synthesizer keyboard. These sounds cover the spectrum of acoustic pianos, reeds, brass, string instruments and other sounds where the PCM technology showed its brilliance. The internal engine contains 64 PCM sampled sounds and 64 more could be accessed from the optional memory cards. These cards were the same as those used with the U-110/U-220 modules and the U-20 synthesizer.

The CM-32P module had fixed MIDI channels 11 through 16 and was intended as an add-on to an existing CM-32L module giving the user the full spectrum of sounds needed for MIDI orchestraion. The CM-32P It had a polyphony of 31 notes and contained an effects unit providing reverb and a chorus to colorize the sounds.
