Dropout on program change |
  |

Hi
I've a problem.... in a song if I send a midi prog. ch. in one chanel, the other 3 chanels will stoped to do sound for a second. aftyer that each chanel continue with his ssound.
It's not possible do severals program chang. without this?
thanks a lot to any suggestions.
sincerisly

Unfortunately, this is a design limitation of the G2. You can't change patches without all of the slots stopping for a shot period as the DSP code is reloaded. You can change variations though using CC70. (Someone please correct me if I have this CC number wrong.) Wish I had better news.

bad.....very bad!!!!
thanks Mosc for your answer and yes, i'ts cc70 change variations.
Do you think a new op. sistem will solvet?
thanks again

Anything is possible. I'm not privy to the design plans at Clavia, but I doubt if we will ever see this fixed in the G2. It bothers some people more than others.
I think it would be possible to make it so there is no drop outs, but they would have to fix it to one or two processors per slot.
You can always but a second G2.

The loading ggap is an old limitation of the NMsystem..because the slots share the dsps all of them have to be recompiled...
You can have a sound with 8 voices in slot A that uses 2 dsps alone for example. To avoid the loading gap you need to permanently adress one dsp per slot..leavin you with a much more limited general polyphonie...
I wouldnt mind if ther would be 2 operating modes, but because this chane is so deep in the structure i dont think this is likely to happen.
Think yourself..what would you prefer...more polyphonie or loadinggap only on the slot that recieves the programchanges...
And note that in performance mode you only loose..you allways will
have a loading gap there...
It however would be nice if a singel slot could be locked to a specific patch and dsp, to cover loading gaps..this would be maybe a compromise...
You maybe should request such a feature in the wishlist. |

You can be sure that Clavia has deeply looked into this fact, as if this could be solved they would do it immediately. But it is the price that one has to pay for having a system with a variable patch architecture. On a synth where the patch is always the same, but only the knobs settings are changed, this effect doesn't happen. But there are tons of deep technical reasons why the silence is unavoidable when DSP's are loaded with other patches that contain different modules.
The suggestion of avoiding the little moments of silence by reducing polyphony have been tested, but results were such that you wouldn't want that. On every load of a new patch you loose lots of DSP resources and very soon you end up with just one voice of one sound. Much quicker than you think (or wish), you can trust me in this.
No one has yet found a solution to this puzzle (for the NM DSP architecture), and most probably it just can't be solved satisfactory. |
