CC Processing Latency

Hi All,

I’m trying to control the DT from an external sequencer (Cirklon 2 in this case) and it seems that CC values are sometimes processed late. In my particular example I’m overriding sample slot - I have 8 slices of a drum loop and I’m controlling which one gets played using CC19 as per the manual. If I set up the Cirklon to just iterate through the samples, when I watch the SRC page for the relevant track on the DT it looks good, the sample slot correctly iterates from 1 through 8. However what is played is incorrect, some of the samples get repeated. If I look at the waveform view of the src page, sure enough it doesn’t seem to update in realtime (sometimes it lags). I did some midi monitoring and it looks like the Cirklon is doing the right thing - sending the CC in advance of the note - but the DT is not sufficiently responsive to the CC message to keep up.

I have tried some other parameters as well and have had similar problems. Anyone else run into this? I probably need a sampler designed to be controlled externally, but I loves me my DT :slight_smile:
