Atmospheric Performance: Digitana & FSOL SX-1 With Alina Kalancea

Prepare to be immersed in this 8 minute live video performance by Alina Kalancea featuring the Digitana SX-1. Expect evolving and strangely relaxing sonic atmospherics with some urgency.  

The Digitana and Future Sound of London Synthi-based synthesizer, SX-1, has just been out on its first performance... and quite a perfomance it was too.

Here's some details on the SX-1 Stand Alone Expander. Details on price and availability are still to be released... but after this video we imagine demand could be even greater than before.

DUAL ANALOGUE VCO

Each VCO features sine/triangle and square waves and 'wave-folding' (voltage controlled) that adds higher harmonics/distortion to each waveform for amazingly rich and varied timbres, even unfiltered! Each VCO is frequency controllable via CV1 or CV2 which can either be external or MIDI generated from the built in MIDI-CV converter or 'free running'. The frequency range of the VCOs is very wide, from LFO to high frequency audio. Two modulating waveforms are available (speed controlled by the Sample & Hold clock or LFO) via toggle switches to modulate the wave-folding of VCO1 and VCO2. These same waveforms are also available to modulate CV1 and CV2. All VCO1 and VCO2 waveforms are individually available either 'pre' or 'post' the filter/envelope/delay/distortion sections via 3.5 mm jacks.

SLEW LIMITER

A Slew Limiter (SL) which acts on CV1 and CV2, with separate control over the amount of slewing applied to a rising or falling input voltage ('attack'/'decay') by front panel pots. The slew rate is switchable between linear/logarithmic response. The latter allows for long slew times. Obvious applications of the SL is adding portamento (glide) to a pitch CV. The SL also has an invert toggle switch that inverts as well as slews the input. With attack and decay levels set at zero the SL can also thus act as a standard voltage inverter.

OCTAVE SHIFT

Octave Shift is controlled by two front panel rotary switches, giving octave shifts of plus or minus three octaves, independently on CV1 and CV2.

LFO

Choice of triangle or square wave forms with variable shape. Hi/lo frequency ranges.

SAMPLE & HOLD (S&H)

LF398 based S&H with variable clock (panel LED shows rate). Input source is either from the LFO or the output of the slope generator.

DUAL ENVELOPES, ATTACK AND DECAY TYPE

Triggering via gate signals g1 and g2 (which can either be external gates or MIDI generated) or by the output of the slope generator. Bypass options are on each.

DUAL FILTERS, 24 DB/OCTAVE TYPE

Voltage controlled frequency with S&H or slope generator CV sources. Bypass options on each. 

ANALOGUE (BBD) DELAY

Analogue (BBD) delay section with a choice of audio inputs and voltage control of feedback via LFO or slope generator outputs.

SLOPE GENERATOR

Voltage controlled rise/fall envelope source with triggering via gates g1 or g3 (which can either be external gates or MIDI generated). Pot control of rise and fall times and levels. A toggle switch allows the generator to be in either one shot or auto re-cycle mode.

DISTORTION

This section can overdrive the audio output of the delay section with added LFO modulation.
