midi drum track dropping notes during playback (noob here)

[mortimertoast]

Heya!

I've used the micro sampler in Waveform to manually program drums for a new song, but when I listen back, notes start dropping out after four bars. It doesn't matter where I start the playback, four bars will play perfectly, then it all starts falling apart. I haven't had this problem on any other projects, and I'm thinking this has something to do with the new midi drum track being a bit busier than anything I've done previously.

I've tried increasing the buffer size, but it didn't help. Does anyone have any ideas?

Thanks much.

Check how long are your samples. Sampler has maximum polyphony, and if samples are too long they can overlap.
