–| DRUMBO MANUAL |–

SYNCUSSION original algos :
- red : osc1 (triangle)
- orange : osc2 (tri) modulated by osc1 (tri)
- yellow : osc1 (tri) and osc2 (tri)
- light green : osc1 (tri) and osc 2 (tri) both swept by env2
- green : osc2 (saw) modulated by osc1 (tri)
- light blue : osc1 (noise)

DRUMBO specific algos :
- blue : osc2 (tri) modulated by env2, vcf modulated by osc1 (tri)
- purple : osc1 (tri) modulated by osc2 (tri), noise and osc2 (tri) into vcf
- pink : metallic oscillator
- white : osc 2 (tri) modulated by metallic osc, vcf modulated by noise (pink)

• MODULATIONS :
- LFO applies to the TUNE slider
- SWEEP correspond to TUNE env
- S&H applies to pretty everything except overdrive
- OD is placed at the end of chain

• SLIDERS :
- TUNE : pitch
- DECAY : decay time for the VCF cutoff env
- WIDTH : (depending of the algos) controls either the VCF cutoff and the amount of modulation in the signal path.
- SWEEP TIME : controls the TUNE env sweep time
- SWEEP RANGE : controls the TUNE env sweep range
- LFO RATE : controls the LFO speed
- MOD DEPTH : controls the LFO amount of modulation applying to both osc
note : each slider acts as an offset when something is plugged into its corresponding output.

• BUTTONS :
- LFO/TRIG : switch LFO on/off, white led flashes when trig is on, orange led indicates LFO is on
- EXP/LOG : switch between exponential (white led) and logarithmic (orange led) pitch mod curves
- TRI/PULSE : switch between LFO waveforms (white led for square, orange led for triangle)
- OD/S&H : switch overdrive on/off + S&H global modulation on/off
push 1 : yellow led indicates that OD (overdrive) is on
push 2 : white led indicates that S&H (global modulation) is on
push 3 : orange led indicates that both OD + S&H are on

• INPUTS :
- MODE CV : scan thru the 10 modes (0 +5v)
- VCO CV : voltage to TUNE slider position 1v/oct (0 +5v)
- DECAY CV : voltage to DECAY slider position (-5v +5v)
- VCF CV : voltage to WIDTH slider position (-5v +5v)
- FORCE CV : controls the strength of the TRIGGER input (0 +5v)
note : since i don't own the module anymore i'm not absolutely sure about the ranges

@plragde

The mixer issue isn't so much digital vs analog as whether it can handle a hot signal, and I think most can. The Presonus Studio Live seems to have a gain control that can lower as much as -20dB, which should be enough (-13.5dB is what's needed). But I still think it's much easier to have an output module and not worry about any of this.

Thanks, i didn't even seen that -20db on the pot..

@JimHowell1970

you'll almost definitely need more vcas then... they are one of the most fundamental parts of a synthesizer... they are incredibly useful for modulation as well as audio - and being able to be used individually is very helpful

I planned to get some attenuators yes, and i heard that Veils had amplifiers that actually amplify.
Ok, now what's the difference between unipolar attenuators and vcas (for which ones don't amplify) ? I ask because i'ld prefer add attenuverters if they can act like "bipolar" vcas..

doesn't the studiolive have a headphone socket? attenuators are always useful!
there's a great headphone module from alm busy circuits called hpo

Yes it has. But i leave my 32 tracks at home when I travel :)

the outputs from tex-mex are modular level... really your mixer should be fine...

Regarding all the comments, yes it should be fine.

Besides that, for the MI Stages, I wonder if the qienem firmware update allows the module to be used as 6 vcas.
Anyway it is a question that remains to be studied, and even if it means remedying it, perhaps it is desirable to solve my I/O issue at the same time. I understand your first comment better.

Thanks all of you for sharing experience.

@JimHowell1970 Here’s the url :
I have a field kit fx for vcas but since it’s a vca mixer they’re merged on the output.. however I may not realise how much I will miss vcas (what you see on the rack url is what I planned to get but haven’t filled all the space yet).
What is a « quad cascading one » ?
For trigger, pitch and gate I also have a keystep and an mpc one (as a midi interface with the rest of my studio for sequencing). I intend to be satisfied with it for the moment given the staggering sums involved in the transition to modular.

Regarding the connection of my system without attenuation to my studio mixer, my mixer is digital (presonus studiolive), so I avoid clipping at all costs then it leads me to always watch the vu-meter (which is right behind me). And, might be wrong but I think attenuators are kind of a second hand solution for my purpose, especially because the output issue comes from the need of headphones socket.

@Cangore thanks, I already took a look on that module and yes it could finally fix all of my needs. But i still expect to find finer solution. Now, regarding that perfection doesn’t exists and since I don’t own an es-9, an harvest man quad pedal send and a proper solution with input gain +30db, I should consider taking 10hp for that.

I have to confess that my case seems too be already too small… 😐

Thank Jim !
I need a solution to :
1. input my studio mixer bus out (to send external synths to my modular).
2. lower the modular output to get into my studio mixer but in fact especially for headphones : stéréo out 1/4 jack (to not need any adaptor) TRS if available and a 'volume' knob.
3. send/return - send modular signal into a Beebo or an Organelle and returning with eurorack level. The Organelle output level is so low that i think it might be guitar level, perhaps so a 'gain in' knob can be very useful.

Don't know if it helps but here's my rack :
https://cdn.modulargrid.net/img/racks/modulargrid_1962355.jpg

I haven't decided on modules 'Befaco Out V2' and 'knob.farm Ferry' yet. In fact, I am a beginner so if you have any advice, maybe a type of module is missing?

Any suggestion ?

Hi,
Is there any reason not to use send/return module as line level input/output ?
As far as, in my case, is not needed the use of both of the two to three fonctions simultaneously, it can merge them in 4 or 6hp.

Why not ?
