Hi, I've just mail-ordered the Clavia Nord Modular G2 Engine today and I cant wait to say hello Very Happy

I am not a keyboard player Rolling Eyes I am going to control the G2 with a guitar (Axon AX100 MKII midi converter).

I am also wondering what the G2 will do with the sound of my guitar if I connect it to the G2 audio inputs. I can't wait to try it Razz

Any other "ModularGuitarists" here?

Regards,

Manuel

welcome Manuel.

I'm not using my G2 in that way, so I'll leave the specifics about that to others.

As a moderator I moved your post to a more general forum, this could turn out to be FAQ item after all, but we'll see about what to do when that happens.

welcome

I consider myself a ModularDidje player Wink

I know of several members combining modular systems & guitars here on the board. Feel at home to ask lots of questions (everyone's a newbie at one thing and an expert at something else here). Oh, and this is about the music so please post your results Smile.

I played around with this a lot with a colleague's midi guitar (roland GK-2A + GR1). The most important part is making sure the pitchbend setting for the patch on the G2 matches the guitar synth (most likely it will always be 12). Other than that most patches sound really good and are very fun to play with the guitar (I'm a guitar player myself).

If you want to make the sounds even more expressive, take the unprocessed regular guitar output and plug it into one of the G2 inputs. Route the input to an envelope follower in the G2 and then patch the envelope output to something like the filter cutoff (or anything else you might patch an envelope too). This makes it feel a little more "guitar like".

Have fun.

Bassplayer here plus some occasional guitar manglings, unfortunately without any guitar/bass midi systems. But with just the sound output from a normal instrument there are sooo many things to do. If you use the audio inputs, make sure your line level is well adjusted to the G2 ins. I have found many preamps to be way too hot for the G2 to handle without clipping, so you might have to turn down a few knobs. Other than that, I think clavia modulars and real instruments make great combinations.

I don't have a MIDI guitar, but I've experimented a little bit with connecting a guitar to the MIDI ins. Mostly simple stuff like pitch-detecting, connecting the line in to the sync input of an oscillator, wah-wah etc. The possibilities are overwelming. Smile

We (me and my buddy) have tried using a regular electric guitar (ok a special one cuz it's a Les Paul ).

We plugged it into the G2's input, added some amp's to boost the signal (we did not use a pre-amp). Then we added a noise gate and a pitch tracker (or zero cross module). The pitch tracker's gate and the pitch were controlling a simple synth circuit.

And I must say, thay we were playing single notes on your guitar and bending them, sliding, etc, the g2 synth was tracking an triggering the notes correctly. Some glitches like false triggers, etc occured, but with some tweaking it's relatively easy to get past them.

You just can't play chords, unless your guitar has a dedicated output for each pickup/string.

Hope this helped, it's a neat way to control the g2!

Thank you very much for the feedback. I guess it's going to be very fun to play with the red box cheers

While it arrives, I'm very busy reading the great information at this forum (thanks again), messing with the software editor and studying the manual. I think this will be the first time that I read a manual before I start tweaking the gear geek

Cheers,

Manuel

it's fun with guitars, cuz you can assign effects to be influenced by such things as dynamics (using slide module for example on a env follower).

Yes and this is nice when a g2 is triggering samples of those guitar phrases...

Nice ...

Anyone got any wierd and wonderful patches for processing guitar they feel like posting? (I'm more interested in audio processing rather than MIDI guitar stuff)

I would print the G2 manual (pdf file). It feels more real, analog.

I use the G2 with a midi guitar converter, the Axon AX100 Mkii.

The only main problem is that the best way to play midi guitar is useing one midi channel for each string and the G2 can only accept 4, so its ok for bass but limited for guitar!

I keep meaning to get a engine as well so I could have my 6 strings, I also have a rmc fanout box which spilts the audio (from a roland 13 pin midi guitar lead) into 6 channels, one for each string, so the idea is to have 3 midi channels and 3 audio channels going to each of the G2s, then have 6 patches each with an envelope follower from the audio, this could be pretty good I think.

What we really need is a module that can take multiple midi channels and assign them to individual voices in a slot (see http://www.electro-music.com/forum/viewtopic.php?highlight=omni&t=7325 )

Also you have some fine FX capabilities in the G2, have a look at http://www.electro-music.com/forum/viewtopic.php?highlight=murf&t=8289 for an example of a good guitar fx patch.

Cheers

Andy

Actually the G2 accepts 16 channels. Just use a noteRec module instead of the keyboard module and put more than one string's sound generator into each slot.

The reason for requiring a MIDI channel for each string is the pitch bend needs to be separate. The G2 midi note receive does not include pitch bend events, nor is there a module to handle pitch bend Receive. Maybe an external box to translate pitch bend to CC might help but CC are unsigned (unlike pitch bend).

We could always forget about the expressive technique (does anyone want to hear that anyway?) or save some money and don't replace the next two strings that break (less is more).

ah, of course. And there is no PitchBendRecv or PitchBendSend modules.

Yes, sorry my mistake. I should have said 4 channels of pitchbend.

The pitchbend is fairly important as guitar to midi converters use pitch bend for slides, hammeons/pullofs etc, not just for actual string bending.

The Axon you have allows you to send other 6 channels or 1 channel. If you set it to 1 channel mode and set Qauntize to auto it can do a faily good job, but if you slide two strings one will send note on messages and the other will send pitchbend, so use of the whammy bar is off!


Cheers

Hi Andy, The AX100 has one feature on the presets called "StringMode" that by default is set to "Separate", but if you set it to "Common" it will send all 6 strings through the same midi channel.

I'm having a strange problem: when I change one preset at the Axon, it doesn't send the program change to the G2 until I play one note on the guitar. Is it hapening to you?

Cheers,

Manuel

BTW, this is my second day with the G2 Engine and I'm completely amazed! The AX100MKII tracks the notes very fast and the Engine response is incredible.
The 2nd preset at bank1 "BackTo72" mixed together with the real guitar (lead distorted guitar) is incredible. It doubles the solos in a crazy way. I've increase the polyphony of that patch to 6 and it perfectly tracks the harmonies.
well done

I wish to try Richardnixon suggestion:

Hi Manuel,

Read my previous post about "common" or "1 channel mode".

Concerning sending patch changes on changeing presets there is a new version of the firmware that does this, look at http://supporten.terratec.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=1190

Also you should join the midiguitar group on yahoo groups, there are a few axon users there.

Cheers

Andy

i use my engine almost exclusivly to process the flute. when this project started out a couple of years ago, the person i was working with and i were wondering if the flute would need switches for each key to generate midi in order to effectively inform the g2 what was happening (i thought we would need the switches). in the end, this proved unnecessary, as all of the tools needed to deglitch the audio are easily constructed in the g2.

if i were going to use the g2 with guitar, i would probably buy 2 engines, and hack a hex pickup to send each string to a separate input.
