MSRP: Y68,040 ($465US)

Synopsis:

(a.k.a. CX5F in Japan) Bitimbral MSX compatible computer, similar to DX21, with a preset based FM sound module (SFG-01), which has limited programmability without YRM-102 cartridge. MIDI is primitive, only allowing DX7 interface or sequencer output. Architecture Class: FM.

Ebay Description:

The Yamaha CX5M is a (8 voice) bitimbral FM computer, featuring 4 operators (8 algorithms) with dedicated (ADSDR) envelopes, a pitch envelope, an LFO (saw:up square triangle random waveforms), 46 presets, tape and cartridge interfaces, printer and monitor outputs, and MIDI.
