Apologies for a truly noob question, but I'm very new to the whole business of recording music and I haven't been able to find an answer here or elsewhere. For logistical reasons, the computer I use to record (an ancient MacBook) is not the computer I use to mix (a slightly younger iMac).
In an attempt not to choke the MacBook, I set up MT PowerDrums on it. (I'm using Yamaha e-drums.) PowerDrums is pretty lightweight, and seems to work OK. However, I can't get any of the SampleTank instruments to output any audio on that track. It works fine with MODO bass, which is an interesting bit of audio, but none of the instruments in ST3 or ST4 will output any audio.
Is there a qualitative difference in the MIDI audio recorded via PowerDrums and what SampleTank expects? I will try to see if the MacBook can handle running SampleTank, but am hoping that I can at least learn why my naive assumption that MIDI is MIDI is apparently wrong.
Thanks.
