spring reverb module dr mix progress

So did a  bit of messing about earlier, sorry i didnt stream this i really thought it was going to turn out naff. having read quite a lot around on the next about the in's and out's of spring rever driving and recovering this is the most extensive i have found https://sound-au.com/articles/reverb.htm  but after messing about with a bunch of reverb tanks i had sitting around it was quite obvious each tank needed a bit of tweaking with the impedance which is to be expected. but its more a case of just messing around with levels in a round about way, i also found all of the reverb tanks i had had their sleeves of input jacks connected to the case, so in effect made efforts to adjust for impedance pointless. so i have opted for a simpler approach than what i have seen around and without much side effect. 

i will chat more about it but for now this is what it sounds like

the plan! what is the plan

well i have somewhat figured out what i think the module will be like. WET DRY??? no. infact wet dry controls have always got on my nerves personally, having always thought in more of the sense of dry signal and send signal. so i think thats what i'm going to do. a dry and a send knob with CV on both it gives you more control that a single wet dry control. 

in the video there is no dry control that is not added yet, you are just hearing the audio going through the reverb. 

also adding a feedback function, what this is is in essence resonance, i think some reverbs call it swell??? all it does is send the output back into the input which somewhat gives the feeling that the reverb is bigger as it is adding reverb on top of reverb, unless the wave is not moving then it will continue to feedback.... its the same as feedback in delays and resonance in filters, this will also have voltage control. at the end of this video i tried adding a filter to the feedback there is a bit of a change. however ill mess more with that. but anyway i will share some circuits soon! 

the other thing i need to think about after sorting out a circuit is what to do with doctor mix setup. the thing is the power in his c64 setup is DC5v and i think AC9v in a commodore, so likely i will piggy back the 9v power. but im still figuring that aspect out.
