DESCRIPTION
===========
This interface provides a Windows MIDI device interface which receives
events and plays it in real-time. On this mode, TiMidity works
purely as software (real-time) MIDI render.
For invoking Windows synthesizer interface, run timidity as folows:
% timidity -iW (interactively select an Input MIDI device)
or
% timidity -iW 2 (connect to MIDI device No. 2)
TiMidity loads instruments dynamically at each time a PRM_CHANGE
event is received. It sometimes causes a noise.
If you are using a low power machine, invoke timidity as follows:
% timidity -s 11025 -iW (set sampling freq. to 11025Hz)
or
% timidity -EFreverb=0 -iW (disable MIDI reverb effect control)
TiMidity keeps all loaded instruments during executing.
To use TiMidity as output device, you need a MIDI loopback device.
I use MIDI Yoke. It can freely be obtained MIDI-OX site
(http://www.midiox.com).
