8081 - Accent

Image
An accent feature is missing from the SoundForce 808 Snare. Adding one is a matter of replacing a 12V rail voltage with the accent voltage. And that’s where a rabbit hole entrance lies in wait.  So Common The TR-808 has one global accent track where you program steps affecting all active voices with an increased trigger level. There is only one global level setting for the amount of accent. This accent is sent globaly on the COMMON TRIG line to all the instruments.   It’s one of those deceptive tricks of the 808 design which in this case makes it's timing special. The common trig signal is always running and consists of a 1ms pulse on every step. The instrument ("data") pulse, which is sent for each selected step is slightly wider so when they are combined there's no chance of them missing each other.  When AND'd together the result is perfectly in time with every instrument in lock step.    The common trig signal is passed through the global accent control, alter

Some errors and unclear explanations were fixed.  This post first appeard on the SS-30M blog on 02/11/21 808 Snare Continued...  I have been happily using my Mutant Snare since the investigation into 808 snare tuning last year, but I still have an itch to create a solution for tuning the 808 snare in a more flexible way.  The conclusion is that I now have design parameters for my own tuneable 808 snare and as a bonus I figured the vexed problem of Q and the decay time! Mut' Point After considering my options I decided that modding the Mutant Snare was not the way to go. There will be no Mutoid Snare. Instead it will have to be a whole new module to get what I want. However, I have made a list of mods that would not be particularly invasive and would make the Mutant Snare even more flexible. The main idea is to bring the filter CV jumper to a switch. This jumper setting selects between the snappy envelope and osc 1 as the source of CV for the
