	Aha! I've just realised that char* doesn't have to just be 1 character like char does (unless I totally misunderstood char in the first place). So char* should work fine. I'm confused yet again about the functions like ReadScore and ScoreEvent. Do they add strings to your actual csd file to show the new score, or do they tell the active instance of Csound to play the score?

	When Csound is running it maintains a sorted linked list of score events that have been massaged to be in real time starting from the beginning of the performance. ReadScore, ScoreEvent, and InputMessage all appropriately massage the text and insert a new score event into the list. So these functions do not write any external files at all. When performKsmps is called (internally, kperf), Csound examines this list. All events whose times are equal to or less than the current performance time are dequeued from the list and, in most cases, an instrument instance is created or found to perform that event. In C and C++ "char" is a number representing one character of text. ASCII and UTF8 characters are one byte in size (8 bits). In C and C++, a "string" is an array of char that terminates in a null character '\0'. A pointer to the first character in the array is also a pointer to the entire array, the entire string. So a string is typically represented by a pointer to char, "char ". So the string "my string' would appear in memory as: \|m\|y\| \|s\|t\|r\|i\|n\|g\|'\0'\| The length of the string, as e.g. returned by strlen, is 9, but you have to allocate 10 bytes of memory to contain this string plus its terminating null character.

	Mike: Thanks again for an excellent explanation! I understand much clearer now what's going on. I was trying to put the ReadScore before and after compiling the .csd, as I was imagining that it might actually at text to a file or something before starting the performance, but after reading your explanation it was obvious that I had to start the performance first. I am now fully able to send my scores from C++ to csound! Thank you all for helping me get there. Having spent so long wrestling with Csound, I have had time to get about half way to the first simple prototype on the C++ score gen side of things :D Thanks Pete as well for chipping in on the char* subject. I'm gaining quite a detailed knowledge of c++ now. Before tackling the Csound API I thought I was fairly up to speed with C++, but I was quite wrong. I'd never come across -> or ? or char* before (when I first saw this I assumed it was just a pointer to a normal char). If any of you are interested, I'll post up a link to show what I'm working on when I get the prototype up and running, though I dare say I'll be back with some more questions when my project starts to get more complex!

	I'm having trouble using ReadScore to insert a tempo statement. I currently just want a single constant tempo throughout my performance, but if I send a char* = "t 0 180" using ReadScore, Csound reads the t as a w for some reason and tells me its an invalid score statement. I've also tried setting it in the .csd file, but it has no effect, presumably because there's no score statements to apply the tempo to when I compile the .csd. How do you guys deal with tempo?

	You can't do it. When Csound reads a sco or csd file it uses the tempo statements to "warp" the times in beats to absolute seconds and writes the warped events into a temporary file that actually drives the performance. csoundReadScore assumes that all event times are absolute seconds.

	Bugger! And I was hoping to get away with using ints for all the score generation and just multiplying the input tempo by 4 or the like to make it the right speed. You're right though, it will be trivial to generate the timing in full in my scoregen code. I'll just use ints to input the score data and convert it to floats to divide it up dependant on tempo
