In all honesty, everything is currently stripped down whilst I sort the room and work out what direction I want to go in (more analogue synths & reel to reels)
I remember having issues with Sonar playing back songs at slower samplerates and some issues with routing the audio as it was when I used my old m-audio 8r (although that had some samplerate issues too >.<) Some of these issues are more down to my lack of time to be able to delve into things further.
At the moment I am at the stage of wanting to just be able to go back to tracking stuff the simple way :) well, simple ish lol. Without having to worry about samplerate mismatches, clicks and pops here and there or bugs in vsts/daws/mapping software, that seem to take up so much of my time when I want to get down to the nitty gritty lol.
A bunch of synths, linked and fed by midi/patch and meddle as you go....
Controller keyboards are another thing, I really don't like their integration with vsts and lack of knobby/tweak-ability. 2 M-Audio controllers I had, one just randomly died, the other had to be sent back due to issues and I got refunded and that was then replaced with a Novation Impulse 49.
Auto-map has been a pain in the rear, took a few attempts to get it to connect with Live and Sonar, hardly worked when it came to vst (mapping controls/getting them to be remembered correctly).
It's really plasticy feeling too >.< faders are tripe (not to mention that 2 of the drumpad pads no longer light up nor do 2 of the fader buttons...and I would bet I've used them twice in total!!!) Can't be bothered to send it back, I will use it as a bit of a controller/preview synth for my other bits if I manage to get it all set up tidy.
I'm not having a gripe at Sonar, I've had issues with a few pieces of software, some which were solved through later patches, others which haven't.
