Yamaha AN1-x
VA synthesizer

About

Released almost the same time as JP-8000 and Nord Lead 1, by reviews AN1x was always somewhere "in the middle". Lack of instant "knobs on" experience immediately detracted many potentional buyers and it lowered the total score in various magazine reviews. In this article we will just take a look of what's inside this synth, what kind of sound it can produce and how it stands against its two competitors.



In the image above we can see an example of osc sync. This kind of setup is not possible on JP-8000. First, you do not need to sacrifice VCO2 to achieve sync. When engaged, sync function creates another oscillator inside of VCO1 called VCO1 SUB (so we get extra osc). Now lets take a look at Sync PMOD (down right on the image). In this example i choose pitch modulation to be applied to the Slave, but i can choose Master instead (as on image below) or i can choose both. The JP-8000 and many other VA synths would give us just one choice here.

Then AN1x offers me to choose the FM source (not many VA synths in that price range offer that). It can be classic FM with VCO2 (as on image below), VCO1, VCO1SUB (as on image above), ENV's and LFO's (yup, we are getting into modular territory, but we are not finished yet!). Then there is additional FM source (marked with FM SRC1) that modulates the depth. After you choose the source, that's when fun really starts....

Now take a look at FM signal! I can apply it to Master (as it is on the image above - that circled M-S area), or i can apply it just to Slave (as it is on image below), or i can apply it to both. Again, you wont find this feature on many VA's. If you want you can always switch off sync and use classic FM modulation.



Then AN1-x got additional oscillator for noise. On JP-8000 you need to sacrifice one of the oscillators to get the noise. And then one important feature: Ring modulation (AM) behaves like additional oscillator (tone source). Because in the mixer section you can mix it with the VCO1 and VCO2 so you get 3 tone sources at the same time + noise. Of course you can always silence both VCO's in the mixer and only listen to AM signal (a classic way).

Then there is the free envelope generator (an additional envelope that you can apply to modulate anything). And that is not one, but 4 envelopes you can hand-draw or use basic shape presets. The editor (shown in image below) also features tools for smoothing, adding noise, scaling etc. This envelope can be synced to midi or can be set to manual length 1 - 16 seconds. With enough time, you can do anything you imagine with this editor as it can modulate any parameter of the synth. You can do any sound change, any modulation, all precisely edited with this envelope. Only limit is your imagination.



Similar to JP-8000, this synth feature wave shape function. So you can emulate raw oscillators from various analog synths. The saw waves on Juno 60 and Prophet 5 are not the same - each synth has different wave. On AN1x you engage the Edge function and "shape" the saw (or square) wave. Of course, 100% real emulations are not possible, because AN1x don't have the same filter as your favorite analog - however, edge function is very useful to - at least get close.

Just like the JP-8000 this synth also features double mode in which polyphony is halved, but you get two timbral sections, which can play a different patch, or be a part of the same sound (ideal for rich pads). Below is a screenshot from the editor that should give you some idea about the basic signal routings and modulations inside this synth. Editor is a must have for this synth, and you can download it here: http://www.yamahasynth.com/download/an1x/s_an1xed.htm








Sound demos

Below is a collection of sounds that i programmed on AN1-x. Most of them use a touch of chorus or delay, because that is expected in most situations. There is no any additional processing except normalization. First two are multi demos, and other are individual sounds.

 Multi Demo1.mp3 - 03:37
 Multi Demo2.mp3 - 04:55 (Note: Part from 00:00 to 00:30 music composed by Sealed)

Didgeridoo.mp3 - It took me some time to make this one, but it was worth it :-)
DX-7 Tubular Bell.mp3 - Emulation of the famous DX-7 patch.
 Powerplant.mp3 - This one requires good headphones or LARGE speakers.
Forbidden Planet.mp3 - Just for your pleasure.
 Hammond Organ.mp3- Dirty type of hammond.
 Free EG.mp3 - Having fun with free envelope generator.
