Being a guitar player at heart, i’ve had a blast using my voyagers filters to color the tone and make swirling leads with the lfo and a little delay, but i’ve been having a hard time trying to work the filters the way i am imagining in my head. coming from the mf-101, i miss all the funky slappy sounds i could create by bumping the envelope follower. Please tell me its possible to do this in the voyager itself without using the mf-101’s env. out.
I’ve searched the voyagers manual front to back, messed with ext gate input, experimented with all the envelope/gate options within the edit menu of the voyagers OS (im using v3.4), and still cant get the filter to follow the external audio in.
Even when i crank the resonance to just really hear a difference the effect it seems as though the cutoff moves to the amplitude(?) of the external audio input to some extent but its such a small movement that i feel miles away from that slappy auto-wah effect i could sometimes coax out of the mf-101
You can not do it with the Voyager by itself. It has no envelope follower.
You could use any envelope follower that has CV outs to do it. I use a Q118 instrument interface module in my modular to accomplish it.
bummer… Thanks a lot though Just Me. Is there any chance you know of a euro rack module that compares to the Q118? I havn’t made a choice as to which modular format i wanna start working with, but the fact that i have enough rack gear already and all the moogerfoogers makes me feel as though i should just try something different and more space saving.
but so i guess the issue is turning my external audio’s amplitude into a cv message can’t really be done within the voyagers software and takes a whole 'nother circuit? which is an envelope follower?
I guess i am pretty lucky to have two mf-101’s and a mf-107 waiting for me at home to do this… But wont be at home for a month…
could anyone explain basically how you would set this up? Does the signal go directly into the mf101 or the mf107 and then bypassed (or not i guess if that is what i am going for) to the voyagers ext audio input. Where does the env. out plug into? and then do i need some thing else to make it gate or will this not be an issue untill i put osc. into the equation? I dont have a vx-352 so hopefully that is not necessary to make this happen.
Split the audio signal from whatever source you’re using into two. I usually do this by plugging into my firebox, and in a DAW, assigning two seperate mono outs from the same input.
Plug one into the AUDIO IN of the MF-101
Plug the other into the AUDIO IN of the Voyager
Then for CV purposes:
MF-101 ENV OUT → Voyager FILTER CV IN
You will also need to dead patch a cable into the GATE IN on the voyager to get the VCA to stay open.
You could multiply your guitar audio signal, send that to the freqbox and to the audio input of the voyager. Then send the env out to the filters envelope input. I wonder why you want to go this route since you have filters, yet I can see why you might need to do this.
If you want to use the freqbox, then just run through the entire audio chain on the Freq turn the mix all the way counterclockwise and the envelope out to your voyager. This way the freqbox won’t be processing anything but your amplitude. You coudl do the exact same thing with your 101.
Ive found that the voyager’s filters can exactly replicate the EHX Bassballs.
The only problem with the eurorack stuff that ive found is that Moog voltages aren’t compatible. I think Moog’s triggers are +/-5v
Here is what it says about the doepfer modules. I thought of this after I posted.
Signals in the A-100
In the System A-100 there are three types of signal:
Audio Signals
Control voltages
Trigger voltages
Audio Signals are produced by the sound source Modules (such as VCO or NOISE), and lie in the range from -5 V to +5 V (10 VSS). The System A-100 can also let you use external Audio Signals (e.g. Microphone, Electric Guitar, Keyboard).
To interface satisfactorily, the level of external Audio Signals must be brought up to the A-100’s operating level.
Module A-119 (External Input), is ideal for this job, having among other things an internal pre-amp, and two inputs of different sensitivity.
Control voltages, as produced by modulation sources like the LFO and ADSR, are from -2.5 V to +2.5 V (5 VSS) for the LFO, and from 0 V to +8 V for the ADSR.
Trigger or Gate Signals, which start a process or function, are typically from 0 V to 5 V, with the trigger occurring as the leading edge of the waveform shoots up from 0 V to 5 V.
These definitions of the various signals, and the distinctions between them - sound sources and modulation sources - are right in principle, but a modular system like the A-100 often makes a mockery of them. In a modular set-up, all of the modules produce voltages, and can be used as control voltages or triggers, thus blurring the distinction between the various types.
For example, the output from an LFO can be used as an audio signal, as a control voltage for a VCF or VCA, or as a trigger signals for a sequence.
It’s just about true to say that anything can be modulated by anything else, so that a modular system gives the musician extraordinary flexibility and individuality.
The dotcom q118 might work better with all Moog voltages.
Thanks Erik… i do have a cp-251 so i guess i’ll just wait till i get back home to try out those different routings. I feel the same way about the voyagers filters… i feel like it gets a different sound than the two lpfs. Plus I wanna start experimenting with the monophonic midi signal on my midi guitar, thus whyi’d really like to know everything about the voyagers audio in.
Too bad about the euro rack versions. I was under the impression that while they all used different sizes and power supplies that most the modules used similar voltages. But I really don’t want to attenuate everything just to send a gate/trigger signal to my voyager… I’ve always liked the .com style more, i just know that I’ll just have to build my own case and won’t find any of the bizarre modules i will in euro rack format.
You can get a doepfer mini case which is like 32 hp for like 129 dollars so if you want to go eurorack you should be able to. The problem is converting the voltages, and I don’t know squat about all of that at this point.
I found an 84hp eurorack for 29,95 euros, but they can’t ship out of germany. I contacted a music store to see if they will order it for me and ship it here. I haven’t heard back on that.
The cheapest thing to do is get a doepfer diy rack where they sell you the rails and you build yourself a cabinet. their power supply is generally compatible with most.
Really, if you want to go euro you can do it. you can have both formats but you just have to do your reading.
I’ve never had a problem with voltages between my eurorack modular and the Voyager. If you look at the Voyager manual’s VX351 section you’ll see that the Voyager itself uses different voltages for different things. It’s not all +/-5v. For example the envelope is 0-5v, the LFO is +/- 2.5V and the S/H is +/-2v. I believe the trigger/gate is 5v.
I am no guitar expert (still learning), but i find processing guitars in a Voyager gives me plenty of clean wah all over the neck range, and it’s easy to do variable speed phasers/flanger like sounds that are cleaner and more defined than those of a typical guitar effects pedal. The few tricks I was about to tell you turned into a long tutorial like message so I put it into a different thread, for potential users to follow.
