The ALM Busy Circuits Akemie’s Castle is a dual VCO that utilizes Yamaha IC’s to achieve 4 Operator digital FM. Each of the module’s operators features independent waveform sections, a frequency multiplier, and both manual and remote level controls. Each of the operators can be combined in various ways across the oscillator sections, which can be further combined with independent feedback control settings on each VCO. All of this combined produces an incredibly wide range of available sounds.
Additionally, the first oscillator boasts a chord mode that allows for up to 5 chord voices with voltage-controlled inversion.

Authentic digital FM sound for Eurorack with never before seen levels of control
The first section of this video consists of a two voice harmony, with the Malekko Voltage Block sequencing two of Akemie's voices while the Variagte 8+ pings each operator's level in a rhythmic fashion. The next section highlights some of Akemie's percussion and melody functions: the percussive voice is modulated by the Voltage Block, while the bass voice is sequenced by the Make Noise Pressure Points. The third section creates a harmonic arpeggio on top of a drone, with Voice A configured as a droning chord while the Multiplier section of Operator One is modulated via Make Noise Maths and the level settings are manually manipulated to taste. The fourth section shows off some of the module's FM capabilities by pushing them to the extreme. Here, Maths and Frap Tools's Sapel modulate Akemie's Levels, Waveshapes, and Multipliers.
