Having a tone replace another tone in BE

[Guest guest]

Hey everyone,I'm wondering if anyone with more BioExplorer experience than myself would be willing to help me figure out if it is possible to have a tone event be replaced by another one after a  second parameter is met.  

Specifically I'm wanting to have four channels make individual tones for alpha amplitude increases and then to have those tones replaced by a different tone when all four channels summed together break a separate threshold.  I tried having all four channels each play an individual tone and then having a deeper bass tone play over the quieter tones, kind of overpowering them, but it was too much noise and made both my headphones and speakers make weird crackling noises... it was not what I would call optimal alpha enhancing feedback  :-)

Thanks to anyone who knows if this is possible or not! Zumbach
