Alternative to Asio4All (works great, try it!) for Kemper USB recording in Reaper DAW:
*Preferences/Device/Audio Device Settings/Audio System : WaveOut
Input device: Digital Audio Interface (Profil
Output device: Digital Audio Interface (Profil
Sample format: 16 bit
Input Channels: 2
Output Channels: 2
Sample Rate: 48000 Khz
Buffer: 8 x 512 samples
(using the heaphone output for monitoring)
For multitracking Guitar and bass using Kemper's Headphone output:
D.I. gtr track: Set to input- mono- Left (mute this track)
Kemper profile amped gtr track: Set to input- mono- Right
After recording the 1st rhythm gtr part, pan it 100% Left.
In Rig Manager/Input settings, adjust the Panorama control to between 75-100% Right (to taste). Now you can hear the previous recorded take in the left ear, click or drum track in the center, and current playing in the right. By recording in mono, the panorama control does not affect the recorded signal (because both are panned right)
Asio4All is pretty poor in my experience, and really a desperation need only. Random clicks, glitches, and the ever important audio driver reported latency to Reaper were always issues to me. I did try it first, and had the same issues. Using WaveOut (so far) is incredible! I'll be deleting Asio4All from my system.
Many thanks and appreciation to the Kemper team for adding USB recording. Grazie Mille!
I'm still experimenting (and haven't read the manual yet..), but so far it is completely amazing. Looking forward to the Kemper audio drivers when released, but so far this works well. Here's 3 distinct improvements over how I've been recording:
1) The Kemper headphone output is incredible, it sounds great, and now you can use it for tracking and mixing! It's hard to describe, just so much better than the audio interfaces I've used.
2) USB recording sounds exact! 100% exactly what I played and heard thru the headphones is recorded in Reaper. It sounds identical on playback.
I did a test recording vs. my old method, and it's much improved, sounds fuller, more raw? somehow, just totally accurate!
3) Recording latency offset/playback timing- this is always a challenge for me. Does what you play- record and playback perfectly in time? Exactly to the click, exactly as you recorded it? Usually I try to measure and adjust the 'audio driver reported latency', and work with that. Actually haven't measured Kemper USB yet, but just in my 1st test vs. my audio interface it seems spot on, better, tighter than the interface.....
Cheers, and thanks Kemper Team!
