[PD] midi latency test

[David Penna]

Guys (& Gals), 

PLEASE HELP!  I'm running Pd vanilla 0.42-4 on Windows Vista Dell Studio laptop with Pentium Dual Core T4200 (2.0GHz/800Mhz FSB/1MB cache) and 2GB Shared Dual Channel DDR2 at 800MHz, using a M-Audio MIDISPORT UNO 1x1 USB midi interface, and -noaudio startup flag.

I'm running this midi latency test patch with the MIDISPORT In & Outs CONNECTED with a female-to-female midi adapter -- and I'm getting 89's & 90's!!!  Incidentally, I also ran it using the In & Thru jacks of a Korg keyboard, and the results were identical... so something is definitely very wrong with this picture!! 

The worst part about this is that my entire purpose for learning Pd was so I could create a Pd patch to use incoming midi notes to "step through" a series of predetermined notes or chords and send them back out to a midi sound source, for the purpose of "triggering" note / chord sequences in realtime from an electronic drumkit.  I've made the patch... but this latency is killing me!!

BTW, this is my first post here, so please pardon my 'novice-ness'.

Any ideas, anyone????

Thanks in advance,

David Penna
