Hard-Boiled Wonderland v1.01

Free VSTI Hard-Boiled Wonderland v1.01A simple (monophonic) 5 oscillator additive synth (the first oscillator is the root - i.e. the input frequency/MIDI note). Has a scope so you can see what kind of waveform you're creating, although this part wasn't coded particularly well, so it tends to slow down your GUI updates (although not your audio playback, due to the way the VST standard works). It can be switched off by clicking on it, however.

Integrated Doobee VST sequencer and synthesiser

Free VST Instruments Integrated Doobee VST sequencer and synthesiserIntegrated Doobee combines sequencing abilities with a monophonic synthesiser. It is novel in it's approach to sequencing, providing seperate sequencers for note position and also pitch sequencing. In practice this means that it is possible to acheive well specified analogue style sequencing and also a range of evolving 'systems music' melodic sequences. Whilst the above description may sound complicated, Integrated Doobee is intuitive and easy to use, and is suitable for real-time performance and improvisation. Integrated Doobee was designed with Ross Bencina's excellent Audio Mulch in mind. Whilst Mulch offers superlative processing abilities it is somewhat limited in sequencing abilities. Integrated Doobee aims to address this issue. Integrated Doobee has been shown to run in other hosts.
Update (17/6/03). This update improves synchronisation, and adds a visual readout to the tempo slider. In effect Integrated Doobee now handles unusual time signatures more logically, and makes a perfect partner to Dr Liebezeit.

Sophia

Free VST plug-ins SophiaSophia excels in creating intriguing ambiences and modulated sound effects. The initial sound generation results from the accumulation of 4 oscillators and a sub-harmonic wave table. Multiple stages of delay and reverb combine with various low pass / band pass filtering controlled by an LFO network. In addition, two separate low pass filters are after the output stage of channels 1/3 2/4 respectively. All sound processing & signal generation is connected to the master LFO network (parameter blast-m). The LFO network makes it easy to modulate any key parameter without using external MIDI controller modulation. However, all of ABV4 Sophia's parameters are controllable via MIDI control change messages.
