That *could* be (as it's not a drum synth), but it'd be kind of surprising.

Perhaps you could make a stereo recording, the left channel recording the
mic'ed 'tick' of hitting the trigger, the right channel recording the audio
coming from the speakers? You'd say e.g. a loud hi-hat should be recognisable
enough.

Let's keep this thread restricted to the situation with only ALSA MIDI in
routed directly to ALSA MIDI OUT - it's getting hard to keep track of what's
going on :).
