Hiya
It say in the beginner guide that the tone range is from C1 -> C4 (including the two I assume ?) thus that makes 37 notes only ? Do 5V not make room for 49 notes ? |

Well, there are an infinite number of frequencies between 0V and 5V. The outer octaves are "out of tune." It's just the nature of the beast with analog oscillators. Even with 12V system like Eurorack you only use the inner 10 octaves. Likewise a 5V system the outer octave are basically useless; therefore, you only have about 3 usable octaves. Again, yes, you can use those frequencies. It won't make a difference if you are unquantized, e.g., play not playing the Western equal tempered scale. However, if you want to play music, i.e., quantized music, then, you'll be limited to about three octaves with this system.
I don't consider this a limitation because I only had about 3.5 octaves back in my saxophone days.

Plus, some oscillators have a switch to choose between "low" and "high" frequencies, or a suboctave output. So you do get a wider range overall, using multiple modules.

This limitation is technically based, because with a 5V supply, not the full range can be used as reliable control voltage range. The MASTER module provides a bit more than 4 octaves (a few semitones more), but above this,it gets quite nonlinear and therefore useless.
But as already stated, this is only the control range; the actual frequency can be set in a wide range on the oscillators; and from this base frequency, it can be "played" via CV over 4 octaves. which is usually more than enough. Do you think of a special use-case,where a wider range would be necessary for one single sound source / oscillator?
Hope this clarifies things a bit!

I have often thought it would be nice if the lo/hi switch input on the 2osc/d was a 5v input instead of or in addition to being a toggle switch. That way the range selection of the four octaves could be under voltage control.

The MASTER module provides a bit more than 4 octaves (a few semitones more), but above this,it gets quite nonlinear and therefore useless. What I kinda expected - but reading AE modular | Quick Start Guide I got another 'impression'; But as already stated, this is only the control range; the actual frequency can be set in a wide range on the oscillators; and from this base frequency, it can be "played" via CV over 4 octaves. which is usually more than enough. So I could choice the OSC to have say; C3 as it's 'middle' C and then play the range as C1-C5 or C5 as it's 'middle' C and then play the range as C3-C7 - Right ? Do you think of a special use-case,where a wider range would be necessary for one single sound source / oscillator? uuhhhmm not really - a 49-key keyboard then would 'work' for all 49 keys - a 61-key keyboard would be able to do 49 notes for a few of the 'base' tones the closes to C e.i. 49 tones for an A Hope this clarifies things a bit! Unless I believe I understood you but didn't; then it did A LOT ! :)
I don't consider this a limitation because I only had about 3.5 octaves back in my saxophone days. I agree ! BUT the 'option to pick if it's a say Alto- or Tenor saxophone is REALLY nice ? ;O Also THANK you ! :) to the other forum members posting to this thread |

The idea of AE Modular is to have a single supply voltage and based on this simple wiring and cheeper solution related to Eurorack etc!
What I got into my mind is that such concept would also work with e.g. a internal voltage of 10 V or maybe higher power supply. The CD4000 series is working at least up to 15V and there are surely op-amps with higher voltage range. In addition there are a lot of special Music IC's which need more than 5 V power supply!
The oscillator range could be larger too.
But this would be a next generation AExt, which could not be compatible with the current AE Modular!
