Roland • MT-32
A home marketed module with sounds like the popular D-50. It uses the same basic LAS type digital synthesis to create its sounds. And it has some rhythm presets that sound like the TR-626 rhythm machine. However this module is very rough around the edges. It isn't rack-mountable, editing must be done externally (using the PR-100 or computer software), the programmable memory dissapears when turned off requiring MIDI SysEx dumping for memory storage, and it's noisy.
It has 128 sounds grouped into 17 instrument groups like bass, synth, wind, perc, etc. MIDI is implemented for more professional or studio use. The MT-32 is also 8-part multitimbral, one of which is the rhythm track. There are 6 'Part' buttons on the face of the module for useful access to changing patches within a part. The MT-32 is a cheap source for quick access D-50 sounds in a box but remember that it is not very professional and would most benefit newcomers to synthesizer-music who are on a limited budget.
But it's great for playing old MS-DOS games...maybe I'm a geek, but those were the days! Wouldn't sell it for the world - it stays here with my old 486 and MPU-IPC-T MIDI interface ;)
