SoftAmp PSA

SoftAmp PSA is a virtual-analog guitar pre-amp supplemented with noise gate and compressor, all modeled after famous guitar gear that needs no introduction.

Flextron DC14

Flextron is a virtual-analog guitar amp made for KVR DC14. It's based on a concept of the hybrid guitar distortion pedal I've built for myself a while ago. The prototype pedal in its turn was based on two commercial tube emulation technologies – Flexwave by Crate and Cooltron by VOX.

SoftAmp FM25

SoftAmp FM25 is a virtual-analog model of the Fender Frontman 25R combo amp. The Frontman is a versatile solid-state practice amplifier for electric guitar. It's equipped with 10" speaker, has 2 channels that share a 3-band equalizer, and a spring reverb. The SoftAmp FM25 has all that precisely modelled and features a tasty bonus!

SoftDrive GV

SoftDrive GV is a virtual-analog model of the Marshall "Guv'nor" and "Guv'nor GV-2 Plus" guitar distortion effects. The Guv'nor is a solid-state distortion pedal first issued in 1989 to recreate the sound of a cranked up Marshall stack in a small stomp-box format. SoftDrive GV expands on the original design and brings in new possibilities unthinkable of outside of the digital realm.

SPICE vs. VST

Here's a funny thing I've done. I've run a short riff through SPICE circuit simulator of an amp I'm working on and then the same riff through my VST plug-in. Can you spot the difference?

Another teaser

Here's another teaser of the upcoming distortion plugin just to let you all know I'm still here. Perfecting a plugin takes a lot of time! The DSP part is now completed, there's just some minor GUI work left. I've also done the first optimization pass and was able to reduce the CPU consumption 10-fold compared to my initial model. I've got some ideas on how to gain about 2x extra performace increase, but I'll leave that to the post-release work.

News update

I've been silent for a while, because I'm spending all my available time on a new effect. I'm coming up with a new modeling algorithm, far more detailed than what I've used so far. I think it pretty closely models the mixed frequency-dependent/nonlinear behavior of the real circuits rather than breaking them up into separate linear filter/static nonlinearity chains.

Charbooster

CharBooster is a composite overdrive effect tailored specifically to be used as booster in front of any virtual amplifier model. It essentially consists of a pre-emphasis filter section designed to provide a variation of voicings for your instrument followed by a saturation circuit that excites the signal with harmonics while still being as transparent as possible. The UI is not trying to look like a hardware stomp box but rather has a range of meters and scopes to provide an insight on what is going on with your signal.

SoftAmp GT

SoftAmp GT is a virtual emulation of a well-known analog guitar amplifier simulator stomp-box. The prototype is a solid state circuit that uses op-amps to saturate the signal and moderate filtering to shape the tone throughout the signal path. The speaker simulation is achieved by a steep low-pass filter as well as some middle-frequency manipulation to resemble different microphone positions.

SoftAmp 3OD

A single triode stage circuit typical for guitar preamps is captured in this plugin. The model engine is based on a system of non-linear ODEs. Some smart calculation techniques are used to reduce the computational load.
