Default Unexpected delay / latency issue

Hi there,

i am a complete newbie to Reaper and have installed it onto my new DAW PC to try it out. I am absolutely blown away about all the customizations and features but also have a little issue which i couldn't solve myself so far.

My setup includes a I7-6700k with 32 GB RAM and various SSD and HDD drives. Right now i am testing a Behringer UMC404HD audio device that features direct monitoring. My master keyboard is a NI Komplete S88 and i use it to send MIDI data out to my Korg Kronos and my Yamaha Motif workstations. But when doing this within Reaper, a noticible delay can be heared when pressing a key on the NI keyboard to trigger the Korg, for example. As this also happens when the direct monitoring with zero latency feature is turned on, this seems to be a MIDI issue as there is no latency when a key is pressed directly on the Korg's keyboard. Does anyone have an idea why this happens and how it could be eliminated?

I've also noticed a similar issue when playing hardware synths from my Yamaha KX8 with its MIDI routed through REAPER to other hardware synths. I posted a more detailed reply in the thread Amack linked to above.

I'm having a similar problem. I'm using the ReaSamplOmatic5000 VSTi and import my recorded wav file but when I play the note on my MIDI, it seems there's a delay before playing the wav file. Can someone help?

Thx

Actually, this sounds more like an audio latency related issue depending on Audio I/O devices or setup. You should tell something more about your specific setup to receive helpful advice.

I have a homemade MIDI keyboard that just sends MIDI Notes to my laptop through USB. Then I recorded a sample wave file from my instrument (dulcimer) and used ReaSamplOmatic5000 plugin to play back that wave file through my laptop speakers. I tried carefully to start the wav file with no delay. That's where I hear 0.3-0.5 sec delay from the time I hit the key on my keyboard until I hear the wav play back.

I tried a different SW, SynthFont on the same Setup and I don't hear any delays.

Do I have to do any specific setting to minimize the delay?

Thanks again for the help
