after nearly 10 weeks of buying- ----being disappointed --sending back (only to have it lost) a Roland Vr09------I have a new keyboard. Its the Yamaha ck61. It's really good---logical to operate---does what it says on the tin----RELIABLE ----no surprising sounds ---all stored elements come back correctly. The key action is obviously not piano quality, but neither is it plastic organ----its actually 'comfortable' to use . Maybe keys still on the small side (Vr-09 was ridiculous) but OK. The only issue I have IS -----the outputs are NOT 'Line level'-----they are 'instrument level'------I measured them at around 120Mv, stereo----140Mv mono. We have a rather basic setup (for small venue) where all the instruments go directly into the mixer -----not ideal but it suits our purpose. There is nothing on the market that matches 'instr' to Line. So the mixer has to take the strain, with its trims rather closer to the stops than one would like. Anyway I got suspicious when I had to turn my master volume almost to the stops. ----so measured it. Funnily enough there are now some 4 channel mixers which do exactly that----i bought one (£30) ---and it works as advertised which rather surprised me ----but i have measured its outputs and it delivers true 'Line level'. Also it mixes stereo output to true mono (proper summing, not just passive connections). It also mixes stereo/ stereo out. Previously I had to build a small amp/DI box to get my sons guitar to match the mixer correctly, so finding one already built has been good. So happy camper , at last. I can , now from experience, recommend the ck61!!. tara!
