Hello all,
I am looking for some advice on playing standard midifiles on Palm device. I
am dynamically creating them within an application for playback immeadiately
thereafter. I am going about it by using SndPlaySMF:
Prototype Err SndPlaySmf (void* chanP, SndSmfCmdEnum cmd,
BytePtr smfP, SndSmfOptionsType* selP, SndSmfChanRangeType* chanRangeP,
SndSmfCallbacksType* callbacksP, Boolean bNoWait)
Here is what I�ve attempted:
BytePtr smfP;
objsize = sizeof (MSTREAM[0]); //MSTREAM is a single-scripted array
//where the Standard Midi File data is held.
Totalsize = (objsize*c); //c is the total number of positions in the array
bufH = MemHandleNew(Totalsize); // bufh is a VoidHand.
buf = MemHandleLock(bufH); // buf being the ptr to it.
MemMove(buf, (void *) MSTREAM,Totalsize);
//creating the correct size for the midi stream in memory.
smfP == buf; // is this alright ?
error = SndPlaySmf(NULL,sndSmfCmdPlay,smfP,NULL,NULL,NULL,bnoWait);
MemHandleUnlock(bufH);
At the moment I�m sorting out corruptions in the midifiles I have created,
I�m just wondering if someone has experience of this (i.e. writing code for
playing midifiles on Palm) could they let me know if I�m heading in the
right direction please,
Many thanks,
