ALM Busy Akemie's Castle

※please note
Due to the nature of the original chip, clicking sounds may be mixed when moving the operator's level knob. Even if the level is small, it may not be completely zero.
 Also, due to the nature of the chip, extreme settings can cause significant aliasing noise and distortion.

 Akemie's Castle is a dual oscillator that creates sounds using a digital FM algorithm with four operators. The FM chip that is the core that determines the soundYAMAHA vintage (NOS) chipsBy using, it is possible to completely control the voltage of the authentic FM sound.

 In digital FM synthesis, the oscillator that modulates the frequency of the main oscillator (carrier) is called the operator. By making the frequency of the operator an integer multiple of the carrier, it is possible to modulate while maintaining the pitch (similar to so-called phase modulation). The frequency ratio with the operator's oscillator is called Multiplier.

 Combine operators6 algorithmsYou can choose from. Each operator is individuallyWaveform, frequency ratio (Multiplier), modulation levelCan be controlled with the knob and CV. With a variety of algorithms and oscillator feedback control, it is possible to create a very wide range of sounds.

 In oscillator AChords up to 5 soundsCan be issued, and the turning code can be specified by voltage. It has the following features.

• Eurorack's first authentic 4-operator FM synthesis with voltage control
• Two outputs that can be used independently or in combination
• 4 operators / 6 algorithms / 8 waveforms / FM synthesis sound with feedback FM using YAMAHA NOS IC chip
• Turnable rich chord mode that can output up to 5 sounds
• Power supply reverse connection prevention function
• Designed and Made in the UK.
