Hi everyone, I would like to know what is available MIDI-wise for the NeXT. I am working on a performance art piece with a friend and would like it to be driven by a NeXT (or NeXTs). Is there a sequencer that has capabilities like Studio Vision for the Mac? Is there any sequencer available? Specifically we would like to combine synthesized sound with digitized so the ability to trigger a digital file within the sequencer would be great! Also, what of digital sound file editing? What is the best tool available? It seems that the NeXT would be a SUPERTREMENDOUS platform for this project, but I don't have a good feel for what's available. Thanks for any help! Please send mail to murray@csli.stanford.edu - Pete War not make one great! -Yoda

I used to have a midi keyboard hooked up to my 030 NeXT through an
Apple Midi Interface. I was just able to plug it in, and the basic
midi stuff on the NeXT worked. I just got my 040 upgrade, and since
the serial ports changed from rs422 to rs423, this stopped working.
I was able to get things to work again by building a new cable, and
treating the midi side the same as an 030 next serial port. I thought
i'd make it available to anyone else who needs to do this. the cable
is a din8--din8 with the following pinouts:
From the NeXT documentation (man zs):
Mini-din signals on 68030 systems
Pin Signal
1 DTR Data Terminal Ready
2 DCD Data Carrier Detect
3 TXD- Transmit Data Minus
4 GND Signal Ground
5 RXD- Receive Data Minus
6 TXD+ Transmit Data Plus
7 A: RTXC Receive Clock
B: +5v +5 volts
8 RXD+ Receive Data Plus
Mini-din signals on 68040 systems
Pin Signal
1 DTR Data Terminal Ready
2 DCD Data Carrier Detect
3 TXD Transmit Data
4 GND Signal Ground
5 RXD Receive Data
6 RTS Request To Send
7 RTXC Receive Clock
8 CTS Clear To Send
68040 side -- MIDI side
(DTR,RTS) 1,6 -- 1 (DTR)
(DCD) 2 -- 2 (DCD)
(TXD) 3 -- 3 (TXD-)
(GND,CTS) 4,8 -- 4,6,8 (GND,TXD+,RXD+)
(RXD) 5 -- 5 (RXD-)
Note, this cable is not symmetrical, and won't work if plugged in backwards.
