The Yamaha MT-100 Multi-track Cassette Recorder was an analog tool developed to record artists in the late 1980s. It was marketed just before the advent of Digital Audio Tape. It allowed variable speed recording of 4 tracks of audio that could be mixed, merged and re-recorded onto standard cassette tapes.
The Yamaha MT-100 was useful for capturing multi part ideas quickly and simply. Yamaha also created the DX7 keyboard, RX 5 drum machine, RX 11 DRUM Machine and QX1 sequencer. A sequencer is a device that records MIDI Data digitally capturing musical arrangement as code rather than capturing sounds on tape. This was used by people who primarily utilized Samplers and Synthesizers that had a multi-track music sequencer built in.
Direct line in recording from sequencers allowed for clean recordings within a usable dynamic audio range.
