Would love to hear a demo! I don't have a GRAINS atm but it's one i've always been curious about, just never sure whether any of the existing algos offered much that i was interested in.

Grains is IMO a very underrated module, it is the ideal playground for the arduino coder who wants to port his/her/their skills to the modular world. The mozzi library provides so much power. Most firmwares did not work for me neither but the bytebeats one has been een staple in my sound design, that was before I got the ALGODRONE. So now I can run the KARPLUS firmware.

I was daunted at first by the fact that you have to put in some PC work to make your Grains go full power. Now that I'm delving into Arduino for a first time, I'm feeling like you could get a full row of GRAINS' and make a full-fledged synth that way haha! Been reading the Mozzi library stuff yesterday, and watched some videos. Seems like you can make anything from complex oscillators, LFO's and envelopes to Chord synths etc. Would love to try this guys' firmwares once I get the hang of Arduino: He has like a full modular synth on 90% arduino's! And it sounds great! (albeit sometimes a little bit 'stale' maybe? Which is where the row of analog stuff would come in for the grit  ) |

Thought since I was giving the KS firmware a go I'd do a demo as askeds by dizzeesatchel. its a bit rough as but hopefully i do it some justice. Firstly I play with the Grains knobs after loading the firmware. Then: Quantize trigger via triq124 Manipulate the CV using the Deadband Then for all you Dronees I plugged in the Drone38 Then I got greedy and put some delay, chorus and Phaser in. cheers |

If you have GRAINS, I have just written a super simple firmware implementing the KS algorithm. It is very basic (no adjustments to the decay filter rate for example), but it responds to pitch and trigger velocity. The only 'enhancement' I have made is the ability to change the stimulus type between noise, ramp, and square waves. Code can be downloaded from github hereGreat stuff! I've added it to the Wiki page for GRAINS for posterity: wiki.aemodular.com/pmwiki.php/AeManual/GRAINS |

Of course, that is not on-topic for this thread  I should be more consistent with the naming it seems  |

Cool demo, thanks! That gets pretty brutal at times especially with the DRONE, kinda reminds me of Guitar Drag

I used the MULTIFX module with the DUAL DLY program to create Karplus-Strong plugged strings. I made a short video I use GRAINS here. But not with the Karplus Strong firmware but with the euro-pwm-saw-v2 firmware from Ginkosynthese. This is actually a SAW oscillator. But when you turn knob 2 to the right, you get noise. Decrease the delay time (PAR1 and PAR2) on the MULTIFX. Pitch can be changed by playing around with PAR1 and PAR2. PAR3 changes the decay time. Note that I only use the left output of the MULTIFX. The right channel contains too much of the original signal. |

Can anybody here try to recreate this using the DELAY module? I would like to know if the delay time is short enough to use it for Karplus Strong synthesis |

no the delay module is does not provide delaytimes that are short enough. Multi fX does though

Worth resurrecting this thread to say that I just tried my hand at karplus-strong. Grains doesn't make it easy to grab precise pitches for it though. I'd not added other waves besides random noise though -- maybe I should try that?
