I've been running SparkLE 1.6 - 1.7.2b on my windows machine for the past two months. It consumes almost an entire CPU, often glitches the audio (unless I relax my audio buffers from 1ms out to 10ms) (I have a PCIe audio system that can handle 64 channels of audio at 3ms easily). The GUI, with all of it's crap sliding animation, is also very glitchy, slow response, and even leads to the MIDI comm with the controller getting out of sync. I'm only using the master audio, so nothing fancy breaking out all 32 channels. This is true whether I use VST or stand-alone mode. I have no issues with other programs, like Ableton Live9, the Arturia MiniMoog, and all of my Sonic-Core system.
I put it on OSX yesterday, and the processor hit was WAY lower, with no glitches in audio, and that damn sliding graphics interface junk was even a bit smoother. No issues with the controller getting out of sync with the GUI. I need this type of performance on the PC before I use this thing on stage.
What gives? My PC is at least 4x the power of the OSX machine. I can get much larger projects loaded (and running at 32 sample buffers with 24 ASIO outputs to an external mixer) in Ableton on the PC vs. the MAC, so please, don't cry me the OSX is better song.
This screams of bad cross-compiling or testing. Arturia, can you look into this?
