Anyone MIDIing a sound module in the background while running iRealb?

[DaleMac]

Update: I went ahead and bought iRig Midi (Amazon knocked it down to $49.99, no tax & free shipping) and have had a chance to play around with the apps using a keyboard.

GarageBand wins the prestigious "Kiss My Ass" Award. When you switch between voices, it bumps all the internal effects (reverb and echo) back to the default settings. So, if I want to play acoustic piano on some songs and electric piano or organ on others, I have to go back in and reset everything - EVERY TIME. Even if this weren't the case, the acoustic pianos only have 8-note polyphony and the electric pianos only have 6. There is no way in hell any pianist could use it for live performances. Maybe... MAYBE... there's some way to assign more polyphony to a "Track" but I'm not going to waste my damn time finding out. (I wish I had my five bucks back.)

SampleTank and iGrand, both from IK Multimedia, have a problem: If you set "Latency" to Low, there's a slight delay between playing the keys and hearing the notes; setting it to Ultra Low helps eliminate the delay, but if you play anything more complicated than Chopsticks the data stream becomes a train wreck. The keyboards appear to have 16-note polyphony, which is twice GarageBand but still not really enough for serious playing. If I had to choose, the iGrand app loads fastest, is easiest to switch between voices, and has the longest sustain time which doesn't sound looped. But I doubt I'll be using it as a module on any jobs. On top of that, iRig drains the battery pretty fast and I'd either need to recharge between sets, or run yet another cable to some external power source. So, obviously, I won't be purchasing the "Full" versions of either app.
