Stevo3985's Complete Bass Synth v1.5

Hey guys! I finally finished my complete bass synth module. Perhaps a few months later than when I promised it would be done, but better late than never, right? Let me know what you think. I put a lot of hours into making this thing sound good, so I hope some of you will like it and find a good use for it. Also, if anything doesn’t work right or if you have a proposed addition you think I should make, please also let me know. I hope you are all staying safe, happy, and healthy during this difficult time in our world. Be well everyone!

Edit: This is now v1.2, based on some suggestions made by @stschoen, which I think make it better than it was. However, as I was about to post, I read @robertsyrett’s reply, and the perfectionist in me will have a v1.3 in the next day or two :wink:

Anyway, while I am working on that, check out my improvements, as I added a volume knob, straightened out some poly to mono signal changes I hadn’t intended to create, which corrected some signal loss, and I made it truly stereo, whereas it was not before. Also added some pretty lights into outputs 1 and 2 :smiley: Check it out, I think it sounds a lot better today, post-improvements!

Edit for v1.3: Okay, so I think I have worked out all the kinks, at this time. I addressed the hot signal, the detune amount has been changed to be a spread of only 0.2 between positive and negative, as opposed to 0.5, which I think keeps it sounding better overall, and also, the white wire of doom from resonance that @robertsyrett mentioned have all been fixed. Resonance has been scaled down by just 1% and it still has the squeal you can induce by cranking it all the way up, but it does not seem to lock up the module or patch now. I also added some inputs to it, as I figured that more people might want to use it with a sequencer and a clock, without having to make massive modifications to make it happen. @stschoen I invite you to check it out at this time. I think you will like the enhancements and give it your stamp of approval :wink: I hope everyone will. Stay safe, everyone and all the best to you and your families. :heart::slightly_smiling_face:

Edit v1.4: I made another new version which corrected an issue where turning down the att/dec to zero would cause clicks of the filter, kinda like when you would get clicks with a modeled VCA with the env at absolute 0. I also further tuned the detune to lessen the chances of making a horrible sound from the far negative and positive of the knob lol. Just incremental changes, really, so maybe this should have been v1.3.1, but eh, this is just simpler. Let me know if there are any other bugs or changes that need to be addressed. Also, if you end up making something super dope, like @robertsyrett, post it up in the thread, as I’d love to see if/how it is being used. Have a great night everyone! :upside_down_face:

Edit 1.4.1: I started building a VCO from scratch yesterday, and while doing so, I realized that I had done the sync function of the bass synth incorrectly. I have fixed it, and the oscillators are now synced by a phasor node whose output is translated to a square wave, which is running at the same frequency into the sync input of each oscillator.
I am not entirely sure if this is considered ‘hard’ or ‘soft’ sync. Maybe someone else can fill me in on the difference? Whether it is soft or hard sync, it sounds a lot better now that I have the correct function settings. So, v1.4.1 is now attached below. I hope everyone is having a great weekend! :slightly_smiling_face:

Edit 1.5: I added a (pink)noise module to it to try and give the digital filter some more character. It doesn’t sound like the analog stuff I am used to, as I think the stream of bits passing through is overloading the filter node, but that is just a guess. Anyway, it still sounds great and has the intended effect of adding character to the sound. Check this version out. I think I am finally ready to call it done! :smiley:

Interesting use of the reverb node to create the impression of more oscillators!

There are a few things I changed in my copy of the patch. The audio signal was really hot so I added a stereo to mono node before the output. I also scaled the resonance knob about 85% since full resonance resulted in a white wire of doom and I slapped a bipolar indicator on the detune knob, since the synth is only in tune when that knob is in the center posistion.

Here’s a little patch I made as well:

Thanks @robertsyrett! I’m glad that you like it, and thanks for the pointers! As mentioned above, I will be making those changes to make v1.3 in the next day or two. In the meantime, I can’t wait to check out what you made and will be downloading it momentarily! :partying_face:


I’ll look forward to V1.3


@robertsyrett I also wanted to mention your patch, CBS Stuttering Service is so DOPE! Man that was a cool patch, and I feel really honored to have my work included in your project. Thanks for taking the time to make it and share it with me. :slightly_smiling_face:

V1.3 certainly takes the rough edges off V1.1. Great sound, nicely chosen set of parameters with lots of flexibility and a good UI. What’s not to like?


It is now v1.4.1 in the thread. I fixed the sync function, as noted in my edit overhead. I just wanted to comment, as I noticed that adding the new version to this thread did not renew it in the forum. This is hopefully the final revision. :crossed_fingers:

I started to listen to it and I was like “man, that bass sounds familiar!” And only then did I realize you had used my bass module in the track haha I was more than a little sleepy last night when I checked it out. Anyway, sounds great man! :blush:


I guess I have to add a new comment on the bottom to appear in the ‘new’ feed of the forum, rather than just add the edits I made. Anyway, I just completed and tested v1.5 and I think the added noise module gives it a little bit more potential. If anyone downloads it, lemme know what you think?
