- Page 2 All in a very compact form factor, with tons of space for precision and creativity. This module results from a collaboration between Václav Peloušek of Bastl Instruments and Peter Edwards of Casperelectronics. While Edwards’ obsessive attention to detail gave this filter a uniquely balanced resonance and envelope response, the expertise of Peloušek delivered a one-hand user experience filter with a distinctive...

Bastl & Casper’s Ikarie proudly carries the flag of this cinematic world. FEA TURES two parallel filter cores left and right... - Page 4 MANUAL All controls on Ikarie affect each other in a way. It is a very interactive, organic circuit, where all settings matter. The default clean setting to start with would be putting all knobs into center position and resonance fader to minimum. TWO FIL TERS Ikarie has 2 filters.

- Page 8 1 INPUTS - L IN, R IN Connect signal to the L IN and it will be normalised to R IN, unless you connect a different signal to R IN. Turn the INPUT knob to increase input level. Ikarie is super sensitive to the input level and the character of the filter changes a lot under different settings of the INPUT.
- Page 9 4 MOD Use the MOD input to control the CUTOFF of both left and right filters in tandem. The MOD attenuverter knob does not let any modulation thru when in the centre position. Turning it CW opens the modulation for the CUTOFF in the positive direction and turning it CCW inverts the signal and modulates the CUTOFF in the opposite direction.
- Page 10 6 V/OCT Use the V/OCT input as a second modulation input that modulates both filters in sync. This input corresponds to the volt per octave standard, which means adding one volt to the modulation signal doubles the CUTOFF frequency (in other words: tunes the filter one octave higher).
- Page 11 center, the CV at the input will increasingly affect the stereo field in a non-inverted way, and turning it CCW will have an inverted effect. 8 VCA CV This unique filter topology uses a VCA pair for each filter to switch from between the LP and HP modes.
- Page 12 FOLLOW listens to the input after the INPUT knob control, so adjusting the INPUT knob will affect the amplitude of the FOLLOW output as well. ENVELOPE FOLLOWER RESPONSE SLOW FAST INPUT SIGNAL 10 BEYOND Because the two filter signals get subtracted, the resulting spectrum also gets subtracted.

- Page 15 BEYOND STEREO Use the L OUT and the BEYOND output as a stereo pair and use some of the techniques mentioned above. The L OUT gives the sum of the frequency spectrum of both filters and BEYOND gives you the difference. When sounds like that collide in a physical acoustic space, they create a strange disorienting feeling.
- Page 16 PINGING & FM PINGING Use Ikarie as a percussive voice by exciting the resonant circuit with short pulses or noise bursts. INPUT level plays a big part in the sound creation. Take R OUT or BEYOND output, and patch it into the MOD or STEREO input in SPREAD mode to create metallic, alien noises! Use the FOLLOW output to modulate RESONANCE to get even more nuanced control over decay of the sound.

- Page 20 AGGRESSIVE 2 4DB FIL TERING Feed audio to L IN, patch L OUT to R IN, and listen thru R OUT for serial 24dB filtering. Adding INPUT gain, resonance, STEREO detuning or fast envelope FOLLOWer modulation to the mix will result in brutal sounds.
