Re: Using midi to control tempo on EDP
This is a little old but still needed an answer:

correct. although as Matthias says it was kind of a last minute addition,
and we didn't manage to come up with a good way to show the fine tuning on
the display. You can hear it change if you are using the clock out to
another device, and if you tap it enough eventually you see the time

They are. From the standard footpedal you can press Insert and Mute during
TempoSelect to fine tune the tempo, same as with the front panel. If you
use MIDI, the midi VirtualButtons for Insert and Mute also do the same
If you hold the buttons down it continually increments the tempo fine

no. the DataWheel is when we are in a parameter editing state and convert
the feedback knob to a DataWheel. Then it can be used to edit the
quickly, rather than tapping the button a lot. In the case of TempoSelect,
the DataWheel does the coarse adjustment of the tempo.

As noted above, you can use the midi VirtualButtons for Insert and Mute to
do the fine tune of the tempo. Holding them down will steadily change it,
so you don't have to tap it all the time.
The DataWheel function can also be controlled by midi. The Echoplex uses
cc# 6 for DataWheel, which follows the midi standard. So by using cc# 6
during the TempoSelect mode, you would control the coarse tempo adjustment
the same as if you were turning the feedback knob on the front panel.
>Also, how does Overdub work while in SyncRecord mode?
SyncRecord is when you record something in sync to a clock (either
or external), and the start time is not necessarily aligned with the
downbeat. If you want to start recording in the middle of the bar for
example, you can with SyncRecord. You just tap Record right in the middle
and it starts recording. The Echoplex still pays attention to the clock
knows how long the loop is supposed to be. When you tap Record again to
end, it will still round off the cycle so that your loop is perfectly in
sync. From there on it continues to listen to the clock and maintain sync.
On the other hand, if you have Quantize on it will always wait to start
recording at the startpoint (downbeat) defined by the clock.
Overdub works just the same as it always does during SyncRecord. If you
Overdub to end the SyncRecord, it will wait until the end of the cycle,
the record and start playing the loop, and immediately have overdub on.
