Number.b = ReadAsciiCharacter(#File) return is exactly the same as Number.b = ReadByte(#File) Number.a = ReadAsciiCharacter(#File) is this Number.a =Chr(ReadByte(#File)) ? Number.a = ReadByte(#File) only posistive values returned Number.b = ReadByte(#File) negative and positive values returned But 0 or zero, is also the error return of the Readbyte(File) and ReadAsciiCharacter(File), so. To me it all (still) makes some difference as a midi file doesn't handle negative byte-values and can have a many bytes with value 0. To use that source do change this first :

Look for example at the Procedure.l ReadVarLen(File.l) and Procedure.l VarLenToNum(VarLen.l) here Quit a lot do read MIDI files with result = Readbyte(File) in different ways, result declared or not, with masking or not, elsewhere a long (result.l).

#PUREBASIC PLAY MIDI FILE HOW TO#

Trying to find out how to setup a good detection of the 'running status' in midi files I find a lot of sources here which give different undefined errors on analyzing midi-files. Currently, the options are MIDI-OX, LoopBe1, Maple Virtual Midi Cable and loopMIDI.I'm becomming more and more confused on this. The Windows MIDI implementation does not include virtual midi ports and you will need an 'loopback' application that allows you to create them in order to route MIDI data between software. aconnect is a simple commandline program that comes with ALSA, aconnectgui provides a simple gui around aconnect, and qjackctl includes a nice visual routing system for ALSA MIDI. You can then use tools which allow you to make connections between ALSA MIDI streams: aconnect, aconnectgui, and qjackctl (if you are using Jack). LinuxĪs Pure Data uses ALSA MIDI, by default, it creates 2 virtual ports: 1 input and 1 output. To make connections, try the following software: MidiPatchBay or, if you're already using Jack OSX, Patchage.

Now that Pure Data has 2 virtual ports, you can route MIDI data from devices and other software into and out of Pure Data.

#PUREBASIC PLAY MIDI FILE DRIVER#

Next, open PD and select 'IAC Driver Pure Data In' for the input port and 'IAC Driver Pure Data Out' for the output port. Click on the little '+' icon below the Ports list and add two ports: 'Pure Data In' and 'Pure Data Out'. Open the MIDI window and double click on the IAC Driver. Use the Audio-MIDI Setup.app in /Applications/Utilities to create virtual ports for Pure Data to use through the IAC Driver. This allows you to route external MIDI streams into PD as opposed to selecting them manually through the MIDI Settings dialog and most routing software also allows you to save connection settings. With multiple input and output ports, the extra channels are accessed beyond the usual MIDI 1-16 channel numbering:Īnother more useful option is to use Operating System specific MIDI mixing/routing software.

If you want to connect multiple MIDI devices/streams to PD, you can enable the 'use multiple devices' option in the MIDI Settings dialog which enables 4 inputs and 2 outputs. Note: You will have to restart PD in order to connect to new devices that were plugged in after it was last started. You can test that MIDI I/O is working with the Test Audio and MIDI patch: Media->Test Audio and MIDI. Next, start Pure Data and choose the device in the MIDI Settings dialog: Preferences->MIDI Settings. To connect to one of these ports, first plug in the MIDI device (or start your MIDI software). By default, Pure Data has 1 MIDI input and 1 MIDI output.
