CCCC: A Bars and Pipes Tool for generating cyclically varying control change messages. Version: 1.2 (13 September 1997) Author: Richard Hagen R.Hagen@mailbox.uq.edu.au Distribution: Freeware. See the copyright notice in cccc.c. Requirements for running: Bars and Pipes Professional Requirements for recompiling: DICE (or some other C compiler) bars.h and toolstart.c from the Rules for Tools kit. Usage: CCCC is an input tool. It is only useful for generating events when the transport is running, so when it is placed in a pipeline, CCCC becomes the input tool for its track. It can't be used as a padtool. Several gadgets control the functioning of CCCC: CC# (proportional gadget, range [0 .. 127]) This is the number of the control change that you want produce messages for. CC# defaults to 10, the control for panning. Start (string gadget) This is the time (Measure.Beat.Clock) when CCCC should start producing messages. If you try to enter a start value that is greater than the finish value, the start value is set to the finish value. Start defaults to 1.1.0 (i.e. time == 0). Finish (string gadget) This is the time (M.B.C) when CCCC should finish producing messages. If you try to enter a finish value that is less than the start value, the finish value will be set to the start value. Finish defaults to the time of the stop marker for the current song. Period: (string gadget) This is the length (M.B.C) of the oscillation of the control change value. The period can't be set to less than one clock. Period defaults to 1.0.0 (i.e. 768 clocks). Wave (cycle gadget) This is the function that generates the oscillation. Currently, you can choose one of TRIANGLE, SAW, SQUARE or RANDOM waves. Wave defaults to TRIANGLE. Direction (cycle gadget) This is the initial direction of the wave function, UP or DOWN. Direction defaults to UP. Granularity (Bars and Pipes ``pop up note'' gadget) This defines how often control change messages are output by CCCC. The valid granularities are 1/4, 1/8, 1/16, 1/32 and 1/64 notes; whole and half note granularities are difficult to generate, due to the timing of Bars and Pipes transport messages, so if you select them they're automatically translated down to 1/4 note granularity. When a CCCC window is open, and CCCC is producing control change messages, the control change value of the last message generated is displayed in the top right hand corner. Since CCCC generates batches of messages before their output time, values will be shown a little ahead of the their actual passage through the pipeline. Don't be alarmed: this is how the Bars and Pipes transport works - by creating batches of events ahead of time, and sorting out their exact timing only when needed. Important Note: Please note that because CCCC will only produce control change messages when: 1) the transport is running, and, 2) the track it is in is selected for input, or you have multiple inputs selected, and, 3) the current time is between the start and finish times for CCCC. Useful for: Everything! Use it as an LFO. Combined with the Event Mapper and my control change Scaler, you can generate any sort of voice control messages for any purpose: Pitch Bends, Filter Sweeps, Sample Start/Loop Point Modulation, .... Anything! History: Version 1.2 (13 September 1997) Redrew icon. Added the tool type NOTPAD. Version 1.1 (9 September 1997) Made sure the period couldn't be zero clocks. Version 1.0 (8 September 1997) Initial release. If you like this tool, please drop me a line. richard R.Hagen@mailbox.uq.edu.au 13 September 1997
