i have just recieved my quantizer module from robert. i also have a midiclock divider i plan to use these two modules with the sequencer module can someone tell me the best way to patch these modules, thankyou everyone once again for your help

Although I've made videos that explain how the SEQ16 works with the Beat Divider, I haven't yet made a video about the quantizer. I'll do one this evening! For now, if you haven't yet, please watch my video about SEQ16, it might have already most of the info you're after (sans the quantizer of course): |

thankyou very much i will look at your seq16 tutorial again

Yeat heth SEQ16 is a littel tricky, especially if you have any music theory training. those Roman Numerals don't mean the same thing as in figured bass and Roman Numeral analysis!
At any rate, typically the CV out from the SEQ16 goes to the input of the QUANTIZER. From the QUANTIZER to your VCO.
Here's how I use these most often:
CLOCK or LFO > SEQ16 > QUANTIZER > VCO > FILTER, WAVEFOLDER or LPG > out to the rest of the world. Use envelops how ever you like. You get the picture.

Hi williamv, I didn't get around to doing the video that night, but I've found some time this weekend and it kind of turned into a full jam session. You may have figured it out by now, but just in case ... here is my new video where I explain in much detail, how to combine the various modules to play a sequenced melody with the Quantizer: |

Excellent timing. I got my quantiser and cvtool this week. It works as expected with the seq 16 but seems to struggle with wonkystuff rbss. It's like it can't quite decide which note to play. It help a lot if you turn down the cvtool to limit the range. Higher notes are all over the place. I would be interested to know if you've experienced similar and found a solution. Loving the videos, they have been a massive help to a newbie.

Loving the videos, they have been a massive help to a newbie. Sorry meant 2att/CV not cvtool. Hi danbowen, I have just tested this as you've described and I can confirm the weird behaviour where sometimes a note changes halfway or it struggles to find out which note to play. This only happens when either taking the CV straight from the RBSS or when using the 2ATT/CV! I tried the CVTOOL and that problem went away! I'm not sure what is going on, but it seems that the CVTOOL is somehow "taming" the CV from the RBSS so that the Quantizer can deal with it better. |

Yes, apologies — it seems that the output of the rbss has some high-frequency noise on it which ordinarily cannot be heard but unfortunately, since the quantiser is digitally sampling the cv input, occasionally it will read one of these noise peaks. Recent rbss modules (since serial #130) have been modified to reduce this noise, but the already-shipped versions will have this problem. The fix amounts to adding a single 10nf capacitor to the board, and I will write this up on the website soon.
A slew limiter might also help (but I don’t have one to try out)

Thanks for clearing this up namke. I've never noticed this behaviour because I've naturally sent the CV via the CVTOOL from the start. The CVTOOL clears that noise apparently. I can just recommend to everyone to get and use the CVTOOL for clamping random CV (or even from an LFO) into a sensible pitch range before sending it to an oscillator. It makes a huge difference. |

I don't mind attempting a bit of soldering. |

Nice work. I nearly got the cvtool instead of the 2att/CV. They seem to do much the same thing but must be different. |

I've just added a post to the Wonkystuff website describing the issue and its simple fix. I realise that soldering is not for everyone, but I hope that people can find some helpful local to perform the modification as shipping the module back and forth for the update will be prohibitively expensive I'm afraid. wonkystuff.net/rbss-quantizer-issue/ |

Working with lead-free solder is definitely harder, but even for a newbie it only takes a tiny bit of practice. I strongly encourage people to try it or get someone do it, I spent the last three hours just listening to the rbbs doing its thing, not a glitch even without any attenuation! |

I just modified my rbss too. It's like a different module now. Wasn't difficult apart from my old eyes.

Short example of modified RBSS behaving itself. Excuse the quality of video and sound. Err and the music 😄
