Connecting Guitar Processor as soundcard and Midi piano to Cubase

I’m very happy to play through external guitar processor , in my case it’s Mooer GE300, but it can be any other one. I connect headphones and guitar to GE300 and get a really low latency (<5ms) as the WET guitar sound is generated inside GE300, which is almost unachieveble when playing guitar through VSTs. I connect it to PC using USB cable and record it to Cubase with a huge sound buffer set for ASIO driver, as I don’t care about the delay. GE300 acts as a sound card.

But now I bought electrical piano Roland FP10 which has USB-B for midi out and I want to play it through VST.
Should I connect FP10 to the GE300 which has MIDI DIN IN/OUT ?
Or should I connect it directly to PC ? I want to keep my set up with low latency for the guitar.
Should I buy MIDI controller to convert USB-B to midi ?

Should I buy a sound card if I want to play FP10 + VST with a lower delay?
(But I will loose me current guitar set up where guitar is recorded inside GE300 and digitally via USB transfered to PC → Cubase. Maybe I need to sell GE300 and buy sonething with SPDIF output)

I’m not familiar with either devices, but let’s start with the simple bit:

If you connect the FP10 it should show up as a MIDI input device in Cubase. You can use that as the input to an instrument track in Cubase with a VST instrument. That allows you to play and record from the keyboard (onto a MIDI track), hearing the sound of the VST instrument (“VSTi”).

In other words, you don’t need any additional connection for the keyboard; once connected via USB, it is available as a MIDI source for Cubase. No need to use DIN MIDI or anything else to convert USB to MIDI.

Seems to be a very easy set up, I’ll try it first.

Definately I need to lower my ASIO buffer and here I think all depends on the GE300 limited capabilities when it acts a sound card. It does not handle my Cubase project and low ASIO buffer, so I’ll try to go with some cheap sound card, I think to buy ESI Julia PCIe, according to dawbench com it has a really small 4,2 ms RTL.

Some other thoughts:
It is a pitty that Asio/Cubase does not support low latency for piano VST which I am playing and high latency for the rest of the project, or does it? I dont need low latency for everything, just for 1 VST that I am playing.

Can I have 2 soundcards for Cubase? Guitar Processor via USB and PCIe SoundCard?

I think SPDIF from Guitar processor to 1 sound card which is used by Cubase could solve my problem.

It’s not Cubase or ASIO, but physics (and time). You can lower the buffer size while you record and raise it later for mixing. Research ASIO Guard in Cubase, which attempts to do something like you describe.

Not with ASIO, but some have reported success with alternative Windows drivers. Are you using Windows or Mac?

It would. One of the issues with all guitar processors that have digital outputs is that they cannot be synchronized (digitally) with Cubase because they have no input to accomodate a sychronization source. therefore Cubase (or any recording software) must slave to them, which means you can’t have multiple ASIO devices. It’s fine if the only device you want to record is the output from the guitar processor though.

My interface is an RME RayDAT which only has ADAT I/O, connected to that (for guitar) I have an ancient Behringer V-Amp Pro, which syncs via word clock (coax) and the audio is via ADAT lightpipe. This means the computer and the RME RayDAT is the master audio clock source, and I can connect anything I want via ADAT, and also enjoy the rock-solid RME drivers, regardless of the analog I/O.
