+1 for MOTIF XS Piano (and other sounds). I have almost 2 TB of excellent sample libraries (Rapture Pro, Komplete Ultimate, EW Cloud Composer Plus, and just about all the Bolder, Embertone and SonicCouture stuff), but when I can't find the sound I'm looking for, I often turn to that sweet Yamaha keyboard. In addition to some versatile pianos, it's got some great Rhodes and Bass presets, a killer soft legato alto sax, some nice nylon-string guitars, and others.
But you have to look at your waveform after you record and advance the track a few ticks since, at least with my setup, there is a little lag between the MIDI timing and the audio return.
