Support the people that make all of this possible.ĪPPROACH CONTROVERSIAL TOPICS WITH CARE - Discussion posts that are inflammatory, aggressive, or otherwise likely to provoke flame wars, intentionally or not, will be removed at the moderators’ discretion. If you use our community to encourage any sort of IP theft you will be banned, no questions asked. Posts that contain insults, attacks, or conspiracy theories based on your opinion of the value of gear will be deleted. NO PRICE SHAMING - Some equipment doesn’t cost much, some costs a lot. Posts lacking a comment will be automatically removed after 1 hour. “Here is a track I made” or "look at my new synth" is not sufficient since the point is to encourage discussion. LEAVE A COMMENT ON LINK/PHOTO/VIDEO POSTS - Link, photo, and video posts must include a meaningful comment by the OP. Posts violating the spirit of this rule may be removed at the moderators discretion. NO LOW-EFFORT CONTENT - Low-effort content includes: memes, jokes, pictures of boxes/receipts/shipping notifications, pictures of gear without explanation, self-promotion without participation, etc. If you are not willing to field questions then your post will be removed. If you are the manufacturer or developer of a commercial product, please message the mods before posting, but we will usually allow new product promotion as long as you stay to answer questions.ĪNSWER QUESTIONS ABOUT YOUR OWN CONTENT - Links to streams of your music are allowed only if you intend on fielding questions about your production and your use of synthesizers in your music. Links to uncommonly great specials/deals are allowed. NO SALES POSTS - Sale/trade/buy posts are not allowed. Fair warning to all: racism, sexism, hate speech, political intolerance regardless of viewpoint (especially any witch-hunting or brigading), deadnaming, or harassment of any sort will result in an instant and permanent ban. Many of my issues were resolved by replacing the CA3080s after something probably shorted during the negative voltage regular replacement.Įdit edit: you can change the frequency of the oscillation with the filter cutoff frequency slider and the resonance seems to work.NO PERSONAL ATTACKS - Please keep comments constructive! Personal attacks, insults, and bad faith criticism of users equipment or music will not be tolerated. There’s probably more to do once I resolve this filter issue, but this issue is the one that currently confounds me. The filter worked prior to me unnecessarily replacing the negative voltage regulator on board one…in fact everything worked prior to that point (except oscillator b, but I think that has been fixed in the meantime, though I can’t quite tell with the loud filter overpowering everything). I’m just curious if the loud Filter could be caused by the tantalum or the SG3821 failing. I’ve replaced most active components in the filter section except for SG3821 (I just ordered CA3046 which is the modern equivalent of that chip) and I have yet to replace the 5.6 uf tantalum capacitor (awaiting electrolytic equivalents in the mail). Additionally, the master volume control seems to have no effect on the volume of the synth at the moment. Unfortunately, now the filter seems to only self-oscillate and it is very, very loud…there’s no way to turn it off and it over powers anything I do with the oscillators (which you can vaguely hear in the background). Then I put in new CA3080 chips at IC14 and IC27 on board two and it seemed to bring the filter back to life. I replaced pretty much every transistor in the VCA/filter/articulator and ultimately when I threw in a new CA3080 (IC21 on board 2) I was able to get the correct sounds by turning on the Direct Output Mixer knobs (but that seemed to bypass the filter, articulator and contour generator which still didn’t work). Well, I must’ve shorted something at that point because when I turned the synth on after I could very faintly hear the synth functioning but it seemed the VCA had kicked the bucket. I successfully changed the positive voltage regulator which had failed and had read that it was best just to replace both because they would inevitably fail. It stems from me changing out IC11 on board 1 (the -v regulator). I’m having problems with the Filter section of the Sonic Six.
