We are all fans of acoustic drums and drum machines, they each have different characters and strengths. FAC Drumkit combines both worlds, samples and synthesis, in order to provide new exciting and unique sounds. As a rule of thumb, the synthesizer section brings the body of the sound, and the sampler the unique character. Both parts are layered together and contain essential parameters to ensure they won't clash and will sit well together. On top of the samples and synthesizer section, FAC Drumkit brings unique Amp and Pitch envelopes with precise control points to modify the curve in a gentle or extreme way. The envelopes play a very important part in the signal path because, thanks to their flexibility, they allow designing very special transition. Indeed, the envelope of a Clap is probably the best one to illustrate the benefit of such envelopes created with points. The burst kind of sound is very hard to replicate with classic ADSR, it's not the case in FAC Drumkit. Needless to say, thanks to the control points the pitch transitions are also more interesting and precise. The value of each control point can also be altered manually, to set the root note of a kick for example. FAC Drumkit is for everyone, as sound designer you will be able to synthesize your own drums in a fun and creative way. On the other hand, if you are looking for instant results, use the provided presets or load your favourite sample pack in the sample section of the 16 voices. The randomization engine makes the creation of new sounds really easy. Define what you want to randomize and you are ready to go. Remember that instrument category plays a role in the randomization process. For example, if you want to design a drum kick set the instrument label to BD (or use the voice index to get a wider sound palette). It's also very interesting to select a sound you like and start the randomization process from there, in a gentle way or not, thanks to the options available in the voice button (page selector). FAC Drumkit is an expressive instrument, the amount of velocity can be set individually for each amplitude envelope, and the pitch envelopes can be modulated by external MIDI control change messages. The pitch modulation applies on control points or on the whole pitch envelopes. Important: The standalone app is a factory version only and you won't be able to save user presets. Use the AuV3.

Copperhead is an AUv3 digital subtractive synthesizer plugin which draws its influence from the vintage synthesizers of the early 80's. Only now we have multi-note polyphony, a build in arpeggiator, and a host of integrated audio effects. Copperhead features a custom String Machine, the ability to design your own custom waveforms, as well as supporting oscillator sync and various cross modulation effects. Cross modulation is a type of FM synthesis which can be used to morph simplistic waveforms into something far more aggressive and interesting. At the heart of Copperhead are its two oscillators, which support all your traditional waveforms (SINE,SQR,SAW,TRI), as well as SuperSaw, Trapezium, and other user definable types. The app features pulse width modulation and supersaw, as well as a customisable string engine and the ability to create your own oscillator types. The Voltage Controller Filter supports the usual LP, HP, BP and Notch filters in series or parallel configuration, as well as a couple of unusual ones like Formant which allows you to sweep your cutoff to create interesting vowel sounds. Copperhead also features twin LFO's with random and one shot functionality. It also supports Cross, Ring and FM modulators, in addition to low and high shelf filters. One of the great features is the integrated audio gate, which allows you to generate stuttering audio right out of the box. Combined with effects such as Chorus, Overdrive, Delay, Reverb and Auto Pan / Tremelo, and the ability to specify effect order, you have a lot of control over your sound. If that wasn't enough, we also include a 32 step sequencer, with various mono and poly modes with direct control control of various synth elements. We have a built in Preset Manager which groups presets into banks and groups, which supports drag and drop for easy import/export of presets. You can also access your favourites from a special popup menu, or via the built in quick search facility. Copperhead now ships with over 550 presets which cover just about every instrument category you would ever need. ○ AUv3 compatible. ○ Up to 16 note polyphony. ○ 7 Oscillator wave types. ○ Sub Oscillator. ○ PW/PWM on SQR and TRP waveforms. ○ Supports SuperSaw with MIX and DETUNE. ○ XMod / Ring and FM modulations. ○ Osc Sync. ○ 6 types of VCF filter. ○ Low and High shelf on output. ○ Built in compressor. ○ Chorus, Delay, Overdrive, Reverb and Auto Pan effects. ○ Built in Audio Gate. ○ Preset Manager with Bank/Group/Preset section. ○ Supports drag and drop to import/export presets, groups and banks. ○ Supports web transfer of presets. ○ 32 step arpeggiator. ○ More than 550 built-in presets. NOTE: This is an AUv3 plugin which was designed to be hosted in DAW's such as AUM, Cubasis, GarageBand, Loopy Pro etc.
