there are opcodes in the manual that are missing good, simple and/or complete examples. Sometimes there are just plain bugs and the opcodes do not work as they should. This makes that these opcodes like black boxes and make them unusable.
I think an example should clarify immediately why at the time it was necessary to create this particular opcode. Without this, the knowledge can get lost.
If someone knows of an example for an opcode that has been placed in the list below, please let me know.
These are the guidelines for the examples in the manual:
- work right-out-of-the-box
- run in realtime if possible
- sr = 44100 (or 48000 using jack)
- ksmps = 32
- nchnls = 2
- use the "modern" 0dbfs = 1 if possible (as used in Max and PD)
- be simple and clear in the purpose of that particular opcode
I'm testing with Ubuntu12.04 and CsoundQt.
I worked my way through the manual from A -Z twice now, but there are still examples for opcodes missing.
I hope that soon this blog can be deleted because all opcodes will have their examples in the manual and my work is done :)

============================================
I think there are real problems with:
- LPC: a new set of new and streaming LPC opcodes would be welcome
I am happy with the great help i get from Joachim Heintz on "difficult" examples, and others!
Again, if you know how to use one of the opcodes above, create a working example and post it here. It will then be added to the manual.
