Edit 12-27-11 - Revised Guitar Amp sim effect below in last post
Here is my work-in-progress guitar amp. It is really nothing special since it uses standard modules and modules developed by others in this forum. Philter5 helped me with the vaccum tube animation module and cyto helped me with the VU meter. The Cab Size and Feedback module are from Cyborg's amp project. I am experimenting with adding automatic randomizer values to knobs which are what the switches are for under the Cab size and Feedback knobs.
For some reason, I had to remove the low and high self filters from the filter module because under the right maxed knob settings, the VU meters would max out and the sound would not release and the only way to break it was to go into the module and delete a connection to the VU meters (don't quite understand why). I tried adding a selector switch that would go to a dummy module to act as a sort of reset on the VU meters but it did not work as I had it set up.
I am using SynthMaker CM verison so I can't code or use modules created with other versions of SynthMaker, therfore, I can't optimize. If you hook the guitar amp up to a vsti module with a saw osc, it gives the sound some amplification and distortion like a guitar amp does. Still needs some work.

Hi! Good work!
Just about GUI. It seems such impressive animation as Vacuum Tubes should not be behind the wire netting,
maybe in the center? 😉

Thanks lesobrod. You are right about the tubes, kind of loses its wow factor like it is but I was trying for a more realistic look. Of course if it were a real amp, the wire grating vent would probably be in the back anyway, and you would not see the tubes warm up. I will have to work on a different look. Thanks for the input.

Here is the revised amp sim set up as a effect. I was stumped until I ran across Shifrin's MonoPolyPOW module that would work in SynthMaker CM. That allowed me to make the vst mono, therfore an effect. I removed the experimental randomizer modules for the Cab and Feedback adjustments because it sounded so poor in at least Sony Music Studio 7. The biquad filters really amp the sound level so be careful with your speakers. I left the tube animation the way it was, but may change it up in a future revision. Depending on the Feedback setting, the signal can distort considerably. I have included the osm and dll located at box.net due to file size. Here are the links:

hey, I'm not quite sure its "there yet" no offense.
the way you are modeling the cabinent isnt very good. as well, when processing audio through overdrive for guitar amps, you need to reduce alot of the low frequencies for the distortion to break up the guitar properly. as well, the interface is HUGE! I run 2 monitors at 1920 by 1080 and it takes up most of the screen on one of them.

Chris, no offense taken, I did ask for your feedback. Guess I need to go back to the drawing board, study up more on DSP and how amps are actually modeled. Thanks for your suggestions. I look forward to seeing your final vsts.

for me, it was a trial and error thing. my older amp plugins sounded really bad. for one thing though, you get higher gain better than I do. I'm really bad at editing the DSP code in synthmaker, so I just wired 3 distortions together (funny that it worked well though). if you are going to keep your amp to a somewhat clean/light distortion tone, you might wanna consider adding a compressor after the cab. make it brick wall basically. this, plus a bit of EQ is a cheap way to emulate the tube effect.
