A) I cannot run spark in anything but 44.1. I have a brand new geek squad quad core AMD with 8gb ram and nothing but Spark and Ableton and Decadance ever installed.
B) In Ableton as a vst it eats up my processor and can crash. Some presets almost peak the processor in standalone, but no dropouts. Only on the dual core.
C) If I make any changes to the audio settings on my motu ultralite hybrid audio interface (without Accessing the interface settings thru the Spark audio midi settings 'change audio hardware' button) - when I open Spark Standalone it does not connect to controller. I can either-
1)close spark, change the setting back, and re-open spark, or...
2) After spark didn't connect to controller, go to audio midi settings, click audio setting, click change audio hardware, then make some trivial change to settings. When I close the menu after changing a audi setting, BAM the Spark is already connected.
D)The midi clock drifts mildly when I have my other drum machines and synths running with it, with no midi connection. All my other synths and drum machines stay in lockstep together, and Ableton(!) but not the spark, it drifts in time. It interrupts a good jam session. there maybe another issue or two I can't remember at this moment.
I also have a dual core xp w/ 3gb ram that had more issues with the spark than I can list...
I jam it all the time tho, and make it work, all machines have their 'difficulties'. Limitations spawn creativity. I've had so many drum machines along the way, I'm just glad to be able to finally sample and trade em. The Spark satiates my thirst for 'more drum machines than I can conceivably operate and maintain' ;]
Thanks for inquiring, Kevin, I'm inspired by the spark and want to help out.
I need a dedicated spark chipset for my ram slots!
