SP2 DreamBlaster (parallel port MIDI synth)

Description

The DreamBlaster SP2 is based on the original Dreamblaster that connects to the feature port of a SoundBlaster or similar card, providing a modern MIDI synthesizer in a small package.  This version has been redesigned to work with the parallel port, allowing laptops and other MS-DOS computers to enjoy a full MIDI synthesizer.

• General MIDI synthesizer for parallel port.
• Compatible with special version of SOFTMPU, available at https://github.com/pdewacht/softmpu

USING SOFTMPU: DREAMBLASTER S2P MODE

Run SoftMPU specifying the parallel interface to be used and the base port
address of the MPU-401 interface, e.g.

  SOFTMPU.EXE /MPU:330 /OUTPUT:LPT1
  
To enable MT-32 compatibility, add the /MT32 switch to the command line, e.g.

  SOFTMPU.EXE /MPU:330 /OUTPUT:LPT1 /MT32

A Sound Blaster base port address and IRQ can optionally be specified if
MPU-401 interrupts are required.
