8.10.3.4. Transposition Input port
Use this to tell KeyStep which MIDI port will receive the transposition request.
8.10.3.5. Transpose Input channel
Instructs KeyStep which MIDI channel will set the transposition amount.
8.10.3.6. Transposition Latch
This allows you to choose whether a sequence will be transposed momentarily or latched.
With either setting the transposition will happen immediately; the difference is what will
happen once the key is released.
When Latch is Off the sequences will transpose back to the center pitch immediately after
the key is released. When Latch is On the sequences will stay transposed after the key is
released, and continue at that transposition until another key is pressed.
This parameter also affects the way the KeyStep responds to incoming MIDI notes on the
Transposition Input channel.
8.10.3.7. Transpose Center Pitch
The Center pitch decides which incoming note means “don’t transpose”. The default value is
MIDI note #60, or middle C [C3].
So for example, an incoming C3 won't transpose the sequence, but an incoming D3 will
transpose the sequence +2, etc.
8.10.3.8. Velocity
This parameter determines whether the sequencer will preserve the velocity values of the
original performance or set all recorded notes to the same value.
8.10.3.9. Fixed Velocity value
This sets the velocity value for all recorded notes to the same number if the Velocity
parameter is set to Fixed, not ‘As Recorded’.
8.10.3.10. Tempo knob mode
If you’re performing live and you want to speed up the tempo or slow it down without a
sudden change in value, this parameter will allow you to do that.
Jump: The tempo value will respond immediately when the Rate knob is turned.
Pickup: The tempo will not change until the Rate knob passes through the current value.
