This is a demo of the DigiTech SDRUM in sync with the TC Electronic DITTO X4.
gear: Fender Telecaster, Fender Tweed Champ, Celestion G12M, Shure SM57, Cubase.
The Ditto only adopts the tempo of the SDRUM when he hasn’t saved a loop yet.
After you have recorded a loop you can’t change the tempo of the Ditto anymore. But the SDRUM sends signals via midi to start/stop the Ditto in sync. If you delete the loops on the Ditto you will be able to feed in a new tempo with the SDRUM. Hereafter you can record a different part in another tempo.
