 ====== System-1m ====== ====== System-1m ======
 +===== Extra Waveforms =====
 +
 +**1. NOISE SAW**: The Noise Saw takes the traditional sawtooth to another level with the introduction of noise giving a brighter, brassier sound with a fuller bass response when using LPF cutoff.
 +
 +**2. LOGIC OPERATION**:​ A logic operation refers to a gate signal, switched high or low (on or off) based on a mathematical function. There are a number of logic operations that you may have seen in modular synth world such as OR, AND, NAND, XOR… there are many more. In synthesis, these gates provide a semi-random on/off signal for triggering envelopes or can mix signals, including oscillators,​ to create a unique and complex waveform.
 +
 +This LOGIC OPERATION waveform in the SYSTEM-1m features a novel cascaded logic circuit that mixes multiple waveforms to create a special synth tone unique to this AIRA synthesizer.
 +
 +**3. FREQUENCY MODULATION**:​ There are a number of ways to control the pitch of an oscillator: one of which is by using one oscillator to modulate the frequency of another. You can use an LFO for vibrato effects or use an audio-rate oscillator for FREQUENCY MODULATION – also called FM.
 +
 +As the pitch of the modulating oscillator rises (i.e. frequency of the wave gets faster), a very complex waveform is produced which contains overtones normally not available from the original oscillator. These can be harmonic overtones that are great for deep basslines, or non-harmonic overtones that provide metallic, bell-like sounds. The SYSTEM-1m make this complex synthesis process easy with a range of sounds controlled by one knob: COLOR.
 +
 +**4. FM + SYNC**: This waveform combines the same synthesis method as above, Frequency Modulation, but uses oscillator sync with the FM oscillator to produce a more harmonic waveform. Waveform synchronization,​ or “sync”, is a process of modulating a high frequency waveform to generate a thick, aggressive harmonic synth tone. Combined with FM, it can produce a range of harmonics when swept for build-ups and crescendos.
 +
 +**5. VOWEL**: This formant waveform uses a series of waveforms and complex filtering to mimic the human voice. The [COLOR] knob sweeps through a series of vowel-like modulations from “A” to “U” of each oscillator. Modulating the [COLOR] knob with an envelope or LFO via the MOD switch creates some expressive and interesting synth-voices.
 +
 +**6. COWBELL**: The cowbell has become an iconic drum machine sound courtesy of the Roland TR-808. This metallic waveform is also now part of the twelve oscillator waveshapes in the SYSTEM-1m synthesizer. This unique tone now has a suite of controls; add delay and long release for cowbell/pad like sounds or use a snappy amplifier envelope with an arpeggio for a pitched percussive line that you can match, or syncopate, with your rhythm track.
 +
 +To access the six additional waveforms, hold down the [LEGATO] button and turn the OSC1 or OSC2 knob. Use the [PITCH (PUSH GATE)] knob to trigger a note if no other devices are connected to trigger sound.
