Hands-on control of four distinct voices The Lyra-4 includes four analog voices grouped into two pairs. These voices do not follow a standard VCO structure. Their tuning is based on continuous adjustment using custom variable resistors allowing for fine steps across a wide frequency range. Voices 1 and 2 cover lower frequencies useful for bass tones or drones while voices 3 and 4 work in a higher range. Each voice is triggered by a touch-sensitive sensor which connects through the player’s skin. The amount of pressure and the speed of contact affect the envelope response. With gentle strokes the attack is slower while firmer contact produces a more immediate onset. Environmental conditions like humidity can influence how the sensors behave especially during outdoor use. The FAST switch adjusts the release time for each voice pair and affects sensor sensitivity. When engaged voices require higher HOLD levels to sustain which allows performers to control which voices stay active when using the HOLD function. The TUNE knobs offer accurate pitch setting for each voice allowing for custom intervals and scales. The SHARP knob morphs waveforms between triangle and square shapes for timbral variation. FM synthesis with flexible modulation options Each voice pair can operate in FM mode. The MOD knob controls the depth of modulation while switches select the modulation source. You can choose internal modulation from other voices the Hyper LFO the instruments total output or an external CV signal. This makes it possible to move from subtle modulation to chaotic feedback systems. The PITCH control transposes all voices while maintaining their relative intervals. HOLD keeps voices sounding continuously working in tandem with the envelopes triggered by the sensors. The VIBRATO switch adds pitch movement with each voice using an independent LFO for natural variation. The TOTAL FB switch reroutes the main output signal to replace the LFO as a modulation source combining all elements of the synth into a feedback-based structure. Hyper LFO and delay modulation The Hyper LFO consists of two frequency controls FREQ A and FREQ B which generate square waves. You can combine these signals using addition or multiplication. A LINK switch introduces FM between the two expanding the modulation complexity. The resulting signal can be routed to modulate voices or the delay. This allows smooth LFO patterns pulsing effects or unstable modulations depending on the settings. The delay section features a modulation input adjustable feedback and selectable waveforms. You can set the delay to be modulated either by the Hyper LFO or by its own output allowing for pitch bending rhythmic effects and self-oscillation. The feedback loop can become unstable at high settings turning the delay into a sound generator in its own right. The MOD knob adjusts modulation depth while the MIX control blends the dry and delayed signal. A CV input also allows external modulation of the delay time. Distortion and integration with other gear After the delay the signal passes through a distortion stage. The DRIVE knob controls the amount while the MIX knob sets the balance between clean and distorted signals. The distortion interacts with the delay output providing more complexity in tone shaping. The VOL knob adjusts the final output level. Lyra-4 has headphone and line outputs for monitoring or routing to other gear. Two CV inputs allow for external modulation of voices and delay. These inputs are not scaled for pitch tracking but respond well to step sequencers or audio signals for creative modulation. The compact size rugged design and balanced sound output make the Lyra-4 well-suited for both live use and experimental studio work.

It features four independently tuned voices arranged in two pairs each capable of FM synthesis and organ-style sound generation. These voices are triggered through skin-sensitive touch sensors that also shape their dynamic response. A dual-oscillator Hyper LFO provides modulation to voice pairs and the delay section allowing complex movement and cross-modulation. The mod delay supports both external and self-modulation with pitch-bending effects and feedback-based oscillation. Distortion follows the delay and interacts directly with its output for more variation. External CV control compact construction and a clear signal path make the Lyra-4 suitable for studio use or live setups that require hands-on sound design without menu-diving.
