I also was impressed by RCF TT-08 (mark I) but finally went with Bose S1 Pro on my Yamaha CP4. Totally happy with my choice.

I also was blown away years ago by RCF TT08 about the clarity and natural sound it produces. I also think that wood structure helps in that respect. Finally I bought 2x Bose Pro battery powered speakers which are light and cheaper than RCF. Also soundwise I am satisfied now…maybe untill I compare again with RCF…

I also replaced the springs in my PC3K7 and I can confirm it felt as an improvement. But I have to add that last week I bought a PC4-7 and I think this action is even better! It is Medeli action and I know people complain about the 88-key piano action but this 76-key is pretty fine!

No, I am not adressing a specific tracking mechanism, being mechanic, electric or pneumatic. I think that would lead us too far. I just would like to bridge the gap for existing midi controllers towards application in pipe organ emulation. Making sensors in keybeds assignable would already help I suppose? Maybe also a triple-sensor keybed could help?

My Kurzweil PC3K7 succeeds in producing a decent pipe organ sound, thanks to the patches from EvilDragon, but.... when playing baroque music as written by Purcell ao, I feel like not connecting to the instrument. The sound generation is fine but how about the man-machine interface ? It seems that the organ sound PC3K7 is triggered from the high level sensor in the key, with only very small key displacement. This should be fine for Hammond organs etc but not for pipe. I did some reading and found that "pipes begin to speak" only when key displacement is about half of the travelling. In the attached figure you can see when the sound envelops in function of key displacement. Also note that the sound envelop only stops when the key is back in rest position (ie, high trigger sensor level for digital keyboards) Source: http://www.acoustics.ed.ac.uk/wp-content/uploads/Theses/Woolley_Alan__PhDThesis_UniversityOfEdinburgh_2006.pdf Also, it seems that Fatar carries specific keyboards for pipe organs: http://www.fatar.com/Pages/TP_8L.htm These keyboards also feature a mechanical 'snap' to emulate a resistance force caused by air pressure in pipe organs. I expect the trigger points of the 2 sensors to be different from other semi weighted or synth keybeds. Also, as pipe organs are wind instruments, the attack period should not be too short. Looking forward to discuss this matter here further with you guys and hope to find ideas for improvement.

This JBL Eon One Compact has BT mixing https://jblpro.com/en/products/eon-one-compact

Maybe the 8' versus 10/12' effect as other people seem to be satisfied with Motionsound 610/612? Personally, I would like to achieve similar sound experience when playing AP as with headphones on. Focus on the richness of the carefully designed sounds, more than on volume. I think that should be possible with smaller speakers than 10/12'. I will check out Bose S1 Pro soon. They can also be operated by battery, eliminating power cables.

I think the new generation of small battery powered PA systems may become game changers in this area. I was considering 2x RCF TT08 or MS KP408 until I read about Bose S1 Pro. They include a mixer, easy to handle and install and promising sound (still need to hear them live on my CP4) Any thoughts ?

I was not aware of these battery powered monitors but the concept of course makes sense. While doing some research on the JBL, I came across the Bose S1 Pro which sounded even better to my ears (I mean, on Youtube). However, most videos are about singer/songwriter reviews (mainly playing guitar). Anybody that has experience with (2x) Bose S1 Pro as digital piano monitor?

I also am in trade off RCF TT08 vs Motionsound KP408s. Until now I did not have the chance to hear Motionsound (very hard to find here in Europe) but yesterday I had the chance to play my CP4 on a couple of RCF"s. They indeed sound superb, I can get rid of the 'muddy" sound often heard on ac piano, But to get the best out of the RCF, I also needed to tweak mid-high and mid-low similar as PianoMan stated. The CP4 has 5 band EQ so it was easy to do. Of coarse, fine tuning is also depending on acoustics in the test location. Still wondering where to find Motionsound here

I have one, flat M100. Not good enough for keyboards, for sure not for ac. Piano. Input dynamic range also limited, distortion with high input signal. Other monitors can handle higher signal levels. But it is surely useful for singer-songwriter application. i"m looking for keyboard monitoring and learned from technician that wooden cabinets offer best sound. I once had a gig with RCF TT08 and that was the best I ever heard. Would like to hear new Motionsound amplifiers too. Not easy to find in Europe. All the best

In the past Kurzweil did a lot of effort for creating Leslie effects leading to the Double Leslie FX Chains. Given the double fx units, I hope they can still improve on this and maybe even improve on the whole KB3 mode? KB3 is not bad but maybe it can become even better in PC4?
