[1] MTP originated in the middle '80s for the Commodore and Apple II machines, and when the Atari ST implemented its MIDI support.

It has continued to be one of the more popular proprietary sequencers, but hasn't seen any major updates since 2003 (after having been acquired by GVOX) other than 6.8.4 for Windows, which is reputed to have compatibility issues of its own.

MTP's default data rate is 240 ppqn (time base, pulses per quarter note), or can use 480|960, for higher resolution.

MTP's Anastasia font is used for rendering the Notation window's two-stave piano score, and also provides symbols for guitar-tablature display of chording.

Its fixed-size Conductor window at bottom center left in the screen shot allows flexing of tempo, offsetting in real time, by dragging the slider thumb.
