Hello, I am assisting a psychology professor of mine in a project with music perception and psychoacoustics. We want to use a Macintosh II system to trigger MIDI instruments to play, and then record the response times of experiment subjects to various MIDI-induced sounds. The trick is that we want to be able to control things from procedures within a BASIC or C program. Does anyone out there have information about C or MIDI (or even, ugh, PASCAL) toolboxes that are publicly or commercially available? More specifically, has anyone found MIDIbasic for the Macintosh (a commercial package) particularly useful? I would welcome all suggestions as to where to turn next. Please e-mail to the address below. -David Martosko '91 Dartmouth College -- ------------------------------------------------------------------------------- David Martosko E-mail:sage@eleazar.dartmouth.EDU Dartmouth College HB 2216 Phone:(603) 643-4347 Hanover, NH 03755

Time to trot out your Xpander Blaster Beam Ogasmatron patch!!!! Ya HA HA HA HA HA HA HA ha ha ha ha haaaa!!!.... :-) 8-) ;-) 8^) ;^) |^) :^) *===================================================================* | "Like a Captain, whos ship run aground, | | I can wait for the tide to come around... | | ....time stand still."

Start simple. Go with what you know. Try sounds first, then work your way up to direct MIDI to brain control.... ;-) ;-) ;-) ;-) ;-)

David, Depending on the type of "response times" that you want to measure, you may need to be VERY careful. MIDI is far from instantaneous, and in fact is not even really fast. Any library you use for MIDI control will also affect timing, and the timing may vary for different calls to the same code. If you use an interpreted Basic, you may once again have a substantial delay introduced. Some of these factors can even affect the reliability/accuracy of relative (vs. absolute) timings. It is also my experience that it can be hard to use a subjective impression to tell whether your system response is "prompt"; It can be hard to estimate the time between events detectd by different senses (e.g. hearing and touch). -David ucsd!telesoft!dar, dar@sdcsvax.ucsd.edu
