A couple notes from my setup:
WinXP Sp3, Dual 2.8 cpu
Sonar X1b, Maschine 1.6.2, RME FF800 with ASIO drivers
(note that stand alone Maschine without Sonar works perfectly)
I am unable to record midi info at all from the Maschine controller. I am also experiencing very high CPU usage (in the 60 to 100% range) when just playing a simple loop. Higher spikes cause general instability and slowness.
Although my system has been 100% stable with all other software, Maschine isnt quite there yet with X1b. For example, i had to change my ASIO settings to 256 samples where i usually use it at the lowest (64 samples) Also of note, i cant get Maschine's current loop to stop once Sonar starts it.
I have not yet tried launching Maschine in stand alone outside of Sonar. I might try this.
By contrast, Microtonic-- -a similar drum machine without as many samples--- stops and starts and loops perfectly in time, no problems at all.
