RE: Triple play again



My oblique reference to Metheny missing the old gear was to this

Which tracked well but was possibly before his time

Indeed Pat is referring to the GR-300.  I still have a GR-300 that I use with an Ibanez img2010 & Roland GR202 (plus sustainiac stealth pro)

Pat's guitar synth solo on Offramp's "Are you going with me" is stellar.

The author of that premier guitar article has a wealth of info on his site regarding Roland synth guitars.
I've also purchased one of his 24pin to 13pin convertors - works perfectly... with all the inherit delays of guitar to midi.

I used a Roland G707 with GR-700 in the late 80's and really hated the delay... love the access to synth type sounds but that delay was remarkable.  This lead me to getting the GR300... though as a guitar synth it's a one trick pony... it's a hell of a trick.

I have a Roland GR500 and GS500 as well and these track as well as the GR300, the CV out on these can be used to access older synths with CV input... a ton of new modular (and old) gear as well as the new crop of synths showing up with CV included

Not sure though the note extraction is that quick. I do indeed remember also that Axon/terratec stuff did extract pitch information from the transient, then confirming/following using conventional pitch to midi. I *seeem* to remember the best tracking at the time meant a processing time of about 15ms.
Tablet/PC softwares claim 6 ms (though it did not check the reality of the claim). If not deluded, a 100 Hz fundamental would mean a period of 10ms. But transient extraction if accurate wouldn't have to wait for a full period ?

You're not deluded.


"While the GR-300 barely takes three milliseconds to respond, the VG-99/GR-300 took about 23 milliseconds on average."

It seems that the 3mS response is achieved without pitch extraction.

The first "VCO" isn't an oscillator at at, rather a saw tooth generator which is reset every cycle.
(and clipped to even out volume)

However the second oscillator is tunable and presumably a true VCO, I'd guess that it trails the first (?)
