Im not pretty sure if this is a bug but I think it affects the creation of sounds, i choose a perfect loop sample in SMP, but Vital make a clicky noise when it loops, thing that doesn’t happen in a regular sampler, i hope it gets fixed in the future. Thanks!

Could you check if that sample on both the start and then end have a value of 0db? I think this is most likely due to a fade which DirectWave applies
ohh i cheked and it doesn’t, but still rare that doesn’t applies that feature, i made a sample with 0db at the start and end, and the clicky noise is still there (but in minimum volume)

honestly i would really like that you guys improve that aspect since I love this plugin 
I can confirm samples that play fine in other plugins do not loop properly in Vital. At least the ones I’ve tried so far.
Hmm wondering if this is an oversampling issue. Does it click if you’re in 1x oversampling (in the advanced panel)
Yes the click still happens here at 1x Oversampling.
I’m only a novice to plugin development, but could this be an ASIO issue?
No I think it’s an issue in how Vital is interpreting the loop points embedded in a sample.
Confirming this happens for me as well, even with a file that is literally just a constant DC offset. Doesn’t happen with Sample Bounce enabled but Sample Loop disabled. Perhaps it’s interpolating something other than the provided sample content at some stage?
