Hello Everyone,
I'm quite new in this synth world. I have a complete AE system And it works great. I'm trying now to process external audio through the synth. A question I have is, an external audio signal does create a gate or trigger as well as some cv to be managed with through the synth (i.e to create an envelope for a guitar sound or to use it in a sample&hold or logic module)
I'd love your feedback
Thanks!!

Hi daniabalos, you could try this new module SLEW/EDGE wiki.aemodular.com/pmwiki.php/AeManual/SLEWEDGE It can detect changes in rising or falling voltage and send a trigger when that happens. You could then trigger an envelope to change the cutoff of a filter for instance for the incoming audio signal. Is this what you were after? |

I'm not sure what your question is exactly, do you want to generate gate and CV signal from audio ? If so it sounds like you are looking for an envelope follower, unfortunately there isn't any yet available for AE.
EDIT : Actually careck is right, the SLEW/EDGE can be used as an envelope follower, I had forgotten that

That's what I'm after, yes
I want to generate trigger with an audio signal (my guitar for instance) and use it as I could use an oscillator
That Slew/Edge looks like THE thing
Thank you!!

Damn, I think two off them will not be enough for me x) |

I don't know those 6 pole guitar synth. What do they do ? Are you thinking about diying them into AEM ? |

daniabalos , I was not thinking about it until your post mentioned guitar.

Very little noise has been made about the SLEW/EDGE, but being similar to half a DUSG/Math it is a game changer IMO. It opens the gates to a lot of stuff !

My question is, does SLEW/EDGE also allow for logarithmic curves??

It doesn't, but I think that can be patched in by using feedback.

6 ? (it would be fun with one of those old 6 pole guitar synth pickups (Eek!

I don't know those 6 pole guitar synth. What do they do ? Are you thinking about diying them into AEM ? This got me googling around. Hexaphonic of 6-pole guitar pickups are like having a separate tiny pickup for each individual guitar string. These are used by guitar-MIDI controllers to convert the pitch and dynamics of each guitar string into MIDI messages with which to control synthesisers.
It turns out that there was a guitar for an xbox game with a similar pickup. these turn up 2nd hand for less than $50USD from time to time.
that would be a scary bottomless swamp but I am tempted. Not this year though...
However, imagine one of these pickups with a separate preamp and distortion for each individual string. this would create a rich fuzz with little cross-talk modulation between strings so it would sound more organ-like. Imagine then an envelope follower for each string, then a envelope-controlled filter - even just one across th emix of all strings would sound great. I vaguly remember that the Arp Avatar guitar synth in the 70s had a hex fuzz like this and a filter with envelope follower. I remember trying one in a shop when I was a high school student. It was pretty lush.

It was pretty lush.
I had an ARP Avatar, bought from the London Synthesizer Centre. Apparently, only 300 were manufactured and it's reasonably rare now. Another piece of equipment that I sold for "very cheap". I did get it for a good price, but it still required some hard saving.
As an ARP Odyssey without a keyboard, which is what it was, it was a very decent piece of kit. I hooked mine up to a Roland CSQ 600 sequencer and it was Klaus Schulze heaven. The Hex pickup had to be mounted properly (i.e. accurately, and at the right height) so I carved up the scratchplate of my mid-70's Cimar strat copy and off I went - it was difficult to align it, but you did get a folded piece of card that located the strings and the drilling positions to help you.
After a lot of effort to mount it, and a bit of DIY on the guitar, sadly, the synth tracking was appalling, with squeals and note fluctuations that would have made the dive-bombing whammy brigade fall to their knees. The hex fuzz was great, it sounded both fuzzy and clean at the same time.
It was great fun, when it worked, and somewhere there are some late 70's/early 80's recordings of me using both it and a normal guitar sound in a duo with a friend (he had ARP and Yamaha synths). In the end, I sold it (and the sequencer) for virtually nothing and spent the money on some new shiny Roland toys that were coming out. I still have some of those.
Recently, I have been considering a return to the "ARP sound" via either Korg or Behringer. Of course, the new Behringer Cat is an interesting prospect, the Octave Cat being itself a clone of the ARP Odyssey back when it emerged. I always preferred the fragile sounds it made (listen to some mid 70's Klaus Schulze solos) to the bombastic basses, but they were good as well.
It helped that my parents named me Andrew Richard Patrick of course |
