MTG Turbo CPU Features:
* Plug n Play. No soldering required.
* Supports the original functionality including the sequencer and arpeggiator.
* Each sequence can be up to 256 steps (compared to total of 40 steps on the original).
* Sequences are retained in memory even after power-down. The CPU module does not use a battery.
* Power-on settable parameters for clock start mode, arpeggio up/down mode and arpeggio gate time.
* Sequence Tie mode allows for a variety of note lengths.
* Sequence End mode lets you "chain" the two sequences.
