I've been using these hosts: Orion Pro v7.0, FLStudio7, Phrazor and energyXT1 on my AMD 64bit dual-core WinXP HomeSP2 PC, and while I like many aspects of them, none let me work the way I want to. Hopefully you experienced KVR folk can help me choose the best host (that I don't own) after I tell you how I work/would like to work and what I like about the hosts I've used so far.
Okay, the most important thing for me is to be able to quickly map my midi controller rotaries, faders and buttons to VST synths and effects AND to SAVE these maps, so I can quickly load them in future projects. Phrazor lets me do this (this is my favourite thing about Phrazor!), but this brings me on to my next point.
To record high resolution/smooth CC data sent to multiple VSTs (Synths and effects) ideally in separate midi tracks, but most importantly at the same time. Phrazor lets me do this (not in separate tracks), but at the expense of a major bug that stops me from being able to use it live/realtime, namely there are loud pops in audio while recording automation.
Be able to create automation envelopes quickly for any VST parameter and which can be exported as midi files containing CC data.
The above 3 paragraphs contain the most important things for me, but if the host has these I would be very, very happy
Have PDC, preferably automatically set up.
Be able to freeze and unfreeze tracks.
Have a mixer that's easy to link to my controller, a la FLStudio.
Mute and unmute tracks by pressing a button on my controller.
Must be able to drag n drop audio files into an audio track - 16,24,32bit WAVs are necessary, but more format support welcome.
Preferably, I'd like a host that is modular like energy XT, but without the midi-sync problems when using the main view. However, if the host has racks a la Phrazor, then I can live without it.
A proper sequencer a la eXT (and NOT like FLStudio's playlist) with a piano roll that has good shortcuts a la eXT.
Be Stable, and not contain bugs. FLStudio7 is stable for me, whereas eXT and Phrazor aren't (both contain big bugs especially when trying to record midi).
That's all I can think of for now. I tried Sonar6 when I took my keyboard to a mate's house, but had trouble setting up ACT, so would like to avoid that (and Project 5). Also, if I can't find a host that let's me do I what I want, I will very reluctantly buy Native Instruments Kore and load it into FLStudio. I really would not like to do this though, as it is quite expensive for me and also, I've heard there are quite a few bugs with the current verison of Kore.
Thanks for reading, I look forward to hearing any advice that you can give me on this matter
