ai: advanced integrated
M1's ai synthesis is a straightforward combination of PCM multi-samples, digital filter, and effects. M1 was the first synth to digitally integrate all of these at a realistic price range.
M1 is a 16-polyphonic PCM synthesizer with nearly 100 waveforms in 4MB PCM ROM. The samples are processed by the non-resonant digital low-pass filter, and finally by two multi-effectors.
There are 2 LFOs - one for pitch, and one for filter.
M1 has 3 Envelopes for pitch, filter and amplitude. The envelopes have 4 segments. The time for each segment can be modulated by velocity.
The speed of M1's envelope is notoriously slow, and the velocity works rather modestly, compared to today's synths.
2 pair of Oscillator-Filter-Amp can be layered in a Program. Using the Combination Mode, up to 8 Programs can be layered.
Each multi-effector has 33 effect types, including Exciter, Rotary Speaker, Overdrive, etc.
Joystick and Aftertouch can be used to modulate the filter, amp and LFOs.
KORG T Series are the expanded version of M1. They have nearly 200 waveforms in the doubled PCM ROM - 8MB.
M1 was updated to M1EX with the same 8MB ROM.
The flagship model T1 has 512KB sample RAM as well.
