Behringer/ARP 2500 (n° 104) - Subharmonics and low sounds 

For the 1050 : you send the square (for instance) output of an oscillator in the "ext adv" input of the 1050, you set the number of steps (here 7, so the initial frequency will be divided by 7, which corresponds approximately to a minor 14th, or one octave plus one minor 7th), and then you send anything in one of the active steps. Here i'm using the initial audio signal (in the "in 1" input), but you can also send a constant voltage. You can even send various constant voltages in the different inputs, to shape a custom waveform. For the oscillators : in the current setup i have 6 enveloppe generators, which are the limiting factor. So, 6 independant voices if i were to use a keyboard. There are also the six 1047 « filters-resonators » that can be used as 6 extra voices (without EG), but you cannot make sustained sounds that way.

@@lnefpd I'll give it a try but the begining of your explanation i 'm probably not aware of what you can do with that module but sounds like genious ideas... thanks very much for taking the time to explain !

@@smartti1970 Here is another example : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ACzNCQNf4m4.html. The idea of using the 1050 as a frequency divider is not mine, i found that quite a long time ago on a YT video (but i didn't test it right away and then i couldn't find again the video : so the source of the idea will unfortunately remain unknown...).

@@lnefpd thanks appreciate it
