Joel, CODAina, Stefan, and Frank, I've taken your words about playing quietly to heart. (And thanks to Ubizmo and Roderick for their helpful input.) Spending a week in a hotel and a lot of reading on the web have also reminded me of how musicians in general are always searching for quiet ways to practice so as not to bother others.
So... if I've been a bit QUIET on the forum lately, it's mainly because I've been obsessively thinking about and working on Quiet Coda since we got back from vacation: making copious notes & drawings in my Quiet Coda notebook, sourcing needed supplies, and creating both simple and sophisticated prototypes to test ideas.
Remember my injured back? Well, it's been a bit of a blessing in disguise (like potentially so many things in life if we seek the opportunity, the cloud's silver lining). The back specialist believes I tore something, so recovery has been disappointingly slow. In fact, my injury has prevented me from ultrasonically welding the next batch of Codas so we can begin our first major marketing push. (Ultrasonic welding requires a few long days of me personally standing hunched over a machine on a factory floor with no chance to rest my back, which I can't do until I'm a bit more healed.) As a result, I've been forced to focus on other things--like prototyping Quiet Coda.
By the way, I started out testing DIY ideas for you guys, and I'll share ideas at some point. My conclusion, however, is that none of the DIY solutions come close to a dedicated, optimized Quiet Coda. Quiet Coda should be fun, in tune, and satisfying to play, it should provide useful practice that translates nicely to regular Coda, and it should be really quiet. No, you won't want to record with it, but I believe that you'll enjoy playing it and that you aren't likely to bother people in the next room.
A major challenge I'm facing is that I have to be able to convert Codas to Quiet Codas in a reasonable amount of time. Right now, with the exception of shipping help from wonderful Susan, my local workforce consists of, well, uh, me. (My other helpers are online.) That means that I've had to reject overly labor intensive methods for now, and I'm not getting any new molds made in the short-term. But necessity often leads to creativity.
Can we get this done in the short-term? I'm not sure, but I'll keep you posted. There's a chance that I may choose to send out a FEW prototypes. If you are someone who would REALLY benefit from a Quiet Coda, let me know here or at info@CodaEDC.com.
