The four utilities in this folder are for using the Retro AS-1 without a sequencer. With one of these utilities, you can play the Retro AS-1 from an external MIDI controller when you are using the editor, MIDI processor, or mixer.
The default MIDI input in the Retro AS-1 control panel specifies which of these input utilities is to be used by default.
Retro AS-1 Serial Input
If you have a Macintosh equipped with serial ports, and not USB, you can use this utility directly. All you need to do is select whether your MIDI interface is connected to the modem or printer port.
Retro AS-1 FreeMIDI Input
If you have FreeMIDI already installed on your machine (for Digital Performer, for example), you can use this utility to get MIDI from FreeMIDI and route it to the Retro AS-1 engine. You will have to configure FreeMIDI using the 'FreeMIDI Setup' application provided by MOTU before you can use this utility.
Retro AS-1 OMS Input
If you have OMS already installed on your machine (for Studio Vision, for example), you can use this utility to get MIDI from OMS and route it to the Retro AS-1 engine. You will have to configure OMS using the 'OMS Setup' application provided by Opcode before you can use this utility.
Retro AS-1 PC300 Input
The Roland PC300 MIDI keyboard can be connected directly to a Macintosh with only a USB cable. With the PC300 input utility, the Retro AS-1 can be connected to the PC300 MIDI directly without the need for OMS or FreeMIDI. Make sure that you have installed the USB drivers included with the PC300 before you plug the PC300 USB into the computer.
