Yeah it's pretty basic, I've also seen this document a while ago. But I think the idea is still pretty good... I will definitely try this when I have one of these instruments.
I hope there are more parameters midi-tweakable in the Matriarch. It would be very cool if at least every hardware knob had an CC counter part. Then one would only have to connect cables to the right ins/outs to get pre created sounds, which can also be done real fast on stage if you are prepared for it. With everything prewired in this semimodular machines, perhaps I would not need any cables at all (besides the before mentioned aftertouch vibrato) and could recall patches from my "external memory". Perhaps I should send a feature request to Moog.
Just to put everything in context: one of my current projects is a semi professional classic rock coverband and we are playing about 50 songs at one show (that's why such a hack to "save" patches would be very helpful for me, but it is no deal breaker). To be honest, everything I play, I could also do with just my Kronos and it would be good enough for the main audience. But for my personal satisfaction I'm carrying my Rev2 and PEAK with me, because they are sounding so much better, when it comes to analog sounds. I didn't think it would make such a big difference until I heard the first live recordings with the Rev2 after I played it the first time on stage. The Rev2 serves mostly for brass and string sounds, some leads and pads. The PEAK does mostly leads and pads. But I'm still looking for a lead machine that has a true moogy character. I know the Grandmother does not have the same character as a Minimoog and is more similar to the Moog Modular stuff, but when I compared it to the Subsequent I just liked the GM better. And a Model D is not an alternative for me, because besides replicating what Minimoogs have done for decades, it doesn't allow me to experiment the same way a modular system does (I'm not doing cover music exclusively). I even liked the GM sound more than the Moog One. So in other words: For my personal taste, I will get the most moogy sound with the most flexibility out of a Grandmother and hopefully Matriarch. If there were not the rumors about the Matriarch some weeks ago, I would have pulled the trigger already. But I think I will definitely try the Matriarch first and if it sounds "the same", I will buy this one instead. It will cost me more than twice the money, but since it will be some weeks until I could finally get one here in Germany, I will have saved the additional amount until then.
