I have a GR20 guitar synth with midi in and out but no USB and an Alesis QX25 keyboard with midi out only and USB to the computer.
Can I use the keyboard as an interface for my GR20 and be able to input midi to Sonar with the guitar thru the keyboard?
If so, what would the track settings be?

no. you need something like this. http://www.m-audio.com/products/en_us/Uno.html

You will need a midi device with midi-in to connect the GR20 to the PC.

Ah, right. Ok thanks.
My other device is a DR880 drum machine that has MIDI in and out and a USB out.
Could I use that at all?
I've never tried it as midi for anything but I'm just learning now that I got the keyboard and going thru options.

Glenn, I'm unfaimiliar with the GR20 but I do have an Axon. My understanding is MIDI guitars have a unique connector to the device that decodes the MIDI input. So for me my signal is Guitar -> Axon - MIDI out.

From there I can connect my MIDI out to any MIDI in. So I would think if the GR20 has a MIDI out you should be able to connec that up to the DR880.

Regards,

glenn the only way that you could work that is if one of the devices has a midi thru port. http://www.tonalsoft.com/....2005-07-21.17-00.aspx

I agree with Swamp Tooth.. your best bet is the UNO... midi cable in and USB out to puter.

Will work like a charm and it isnt' to heavy on the wallet.

PS - there are a ton of them on EBAY for about$20.

I use my gr20 and record both the audio outputs and the midi in cakewalk.I record through my fast track ultra. I also use the gr20 as a midi controller for th2.

Ok, a thruport, thanks again.
It looks as if a cheap midi/usb is the ticket for the GR20, tho I did try one a year ago and got unacceptable delay. 
Some folks here said it was common on that device so I took it back.
I now know a bit more about buffers so should give it another try.
GSWITZ do you have an acceptable delay with your GR20 when overdub tracking?

if you're talking about punches, milliseconds count. set the punch in/out points on the midi track about a quarter note before and after the section you're going to record then quantize or edit in prv.
