- This is eguitar by Gary Scavone, McGill University, 2012.
-
- This is a program to create a simple electric guitar model using
- the STK Guitar class. The is model is derived in part from an
- implementation made by Nicholas Donaldson at McGill University in
- 2009. The distortion model is poor, using a simple soft-clipping
- expression provided by Charles R. Sullivan in "Extending the
- Karplus-String Algorithm to Synthesize Electric Guitar Timbres with
- Distortion and Feedback," Computer Music Journal, Vol.14 No.3, Fall
- 1990. Other distortion models would be better, such as that found
- in Pakarinen and Yeh's "A Review of Digital Techniques for Modeling
- Vacuum-Tube Guitar Amplifiers," Computer Music Journal, Vol 33
- No. 2, Summer 2009.
-
- This program performs simple voice management if all noteOn and
- noteOff events are on channel 0. Otherwise, channel values > 0 are
- mapped to specific string numbers. By default, the program creates
- a 6-string guitar. If the normalized noteOn() velocity is < 0.2, a
- string is undamped but not plucked (this is implemented in the
- stk::Guitar class). Thus, you can lightly depress a key on a MIDI
- keyboard and then experiment with string coupling.
-
- The Tcl/Tk GUI allows you to experiment with various parameter
- settings and that can be used in conjunction with a MIDI keyboard
- as: wish < tcl/EGuitar.tcl | ./eguitar -or -ip -im 1
-
- For the moment, this program does not support pitch bends.
-
- In the eguitar directory, type:
-
- > make
-
- to compile and then
-
- > ElectricGuitar.bat
-
- to run the program with the Tcl/Tk GUI.
-
- There are many improvements that could be made to this project. In
- particular, you could record real body responses from different
- guitars and use those with the Guitar class. As well, you could
- improve the distortion model and perhaps add some typical electric
- guitar effects, such as an echo. If you find any bugs, please let me
- know!
