YAMAHA AN1X (1997)
Control synthesizer Analog Physical Modeling

Digital synthesizer based on DSP synthesis Analog Physical Modeling.

At first glance, the An1x looks like the previous CS1x, but it is a far more interesting machine.

technical data

info KEYBOARD 61 velocity keys with aftertouch.
Main panel features a 15-characters backlit display, 28 buttons, 8 knobs and a switch selector. On left side there are 2 wheels for pitch bending and modulation plus a ribbon controller.

Back panel terminal connectors:
- Midi interface
- main signal out
- headphones out
- 3 assignable footswitch inputs.

ac Power supply external PSU Yamaha 12V DC +)- Yamaha PA-3b.


edit TECH CPU HD6413002FP16 (family Renesas H8/300H) CPU manages 10 voices polyphony based on analog modeling APM subtractive synthesis.


A basic AN1X patch structure is composed by:

- 2 digital oscillators VCO that can be processed by:
- 1 generated white noise

- Frequency Modulation process


the VCO1 + VCO2 characteristics:

Waveforms saw / saw + pulse /
pulse / pulse +saw
saw / saw+ pulse /
pulse / pulse + saw
Edge smooth yes, up to sinewave yes, up to sinewave
Inner waves 3 in sync mode none
Rect.width yes yes
Detune yes yes
Ringmodulator yes yes
Mix volume yes yes
VCO sync yes, VCO1 > VCO2 yes, VCO2 > VCO1



edit FM
a frequency modulation can be applied to the VCO1 to change its frequency, in which case the output of the oscillator will become the carrier.

structure VCO1 is modulated by VCO2 following 4 algorithms with variable FM depth:
- only by FM
- sync + FM both: sync mode FM applied to master and slave oscillator
- sync + FM master: sync mode FM applied to master oscillator
- sync + FM slave: sync mode FM applied to slave oscillator.


edit PERFORMANCE the AN1x can be played in 8 modes:

- standard play
- unison stack all voices
- dual voices: 5 x 2 voices (assignable to 2 channels)
- stack voices
- dual scenes
- split zone (assignable to 2 channels)
- split unison (assignable to 2 channels)
- monophonic with legato + portamento time
- ribbon can be assigned to filter cutoff/resonance, modulation and pan motion.
- scenes buttons get values snapshots for each oscillator then Midi CC#1 interpolates intermediate values for a morphing effect.

yamaha an1x tech


cv LFO up to 2 delayed modulators (5 shapes: sinewave, square, triangle, saw and sample-hold + a mix of combinations) with variable depth and 5 destinations:


- VCO pitch
- VCF cutfoff
- VCA amplitude
- LFO FM depth (slave or master)
- pulse width VCO PWM.

demo HEAR LFO on Filter

edit ENVELOPE up to 2 EGs:
- EG1 FEG VCF filter: 4 segments ADSR
- EG2 VCA amplitude: 4 segments ADSR
Both EG are also assignable to other parameters including VCO pulse width and VCO pitch.

filter FILTER
digital resonant filter multimode -12/ 18/ 24 dB/ oct slope.
The Key Track setting determines the key tracking of the VCF, changing the cutoff point in accordance with the notes played on the keyboard.


AN1x filter modes:
- LPF lowpass
- HPF highpass
- BPF banpass
- BEF band eliminate

demo HEAR LFO on Filter


filter EFFECT digital DSP section features 3 algorithms categories:
- FX A: 8 reverbs models e.g. hall, stage, room ....
- FX B: 5 delays with stereo panning motion
- FX C: 14 insert effects e.g distortion, pitch, 3-band EQ, phaser, autopan, rotary, wahwah ....

demo HEAR Panning motion

notes entry is directly programmed using the 8 real-time knobs (switch between 1-8 and 9-16 steps) inspired from classic analog sequencers Korg SQ-10.
Special performance FREE VOICE EG records knobs movement in 4 different tracks.


SYNC internal clock from 40 to 240 BPM and both arpeggiator and sequencer are syncable to external Midi clock.

demo HEAR sequenced

features 30 patterns arpeggiators with 9 subdivide modes and 16 steps programmable sequencer with velocity / gate / swing rate/ latch mode demo Arpeggiator

MIDI full implementation of CC# and Sysex exclusives.
Both sequencer and arpeggiator output Midi notes to other external devices.

filter MEMORY
- 128 RAM patches

battery replacement

LEFT Battery replacement is quite easy and not soldered to the mainboard. No internal ROM sounds, factory set can be recalled anytime.
