Subject: International Experimental/MAX friendly venues

Dear Friends,

subject: International Experimental/MAX friendly venues:

I would like to compile a list of venues nationwide (indeed worldwide) that
are friendly to experimental performances - music or otherwise.  Such a list
would be made available for reference on - and would be extremely
useful for anyone planning a trip or tour.

This list would include Name of venue, city, address, URL and contact
information (phone and/or email).  I beg everyone on this list to send any
information they have about known spaces to -- together we
can build a network of places to both see performances and to schedule our
own shows.

Again that address:

Thanks to sensorband for inspiring this idea...

Am looking for a list of "messages to max", ie. messages that begin ; max

Thanks for the direction.

these guys made the VCA based LCS matrices and mixers (the LCS Nova
series is all DSP, not sure where they oem them from).  I have had great
results using their MX-816 (dual 8 x 1 or 16 through) vcas.  I don't know
if they're still in production (this was a long time ago).
they're nice and cheap, as i recall, and blow away (IMHO) the resistor
network devices like the niche.

Subject: improving MSP efficiency

Hi All,

I have been working on using MSP to do simultaneous processing on 4 audio
sources (guitar and Zeta bass, cello and violin) . I must say that I am
amazed with how much of the CPU is used for processing MIDI. (using a
225MHz G3 and an Opcode 64X) I have a patch with multiple groove~ objects
that runs fine at about 45% CPU useage until I start using external MIDI
control. I start to hear lots of random clicks, screen slow down, and often
see CPU useage in the high 90% and even the occasional lock up. I'm not
sure if this is due to OMS or lower functions.

I assume your mats are coming in from MIDI. If so this is a possible cause.
You might try drastically thinning the control input stream. This may not
be enough. Seriously considering using 2 Macs, one for MIDI processing and
control and the other exclusively for MSP. I am exploring connecting them
via Ethernet and either using UDP or CNMATs OSC. Any one done this yet?
