I am absolutely shocked at the sounds of the Z Filter. The built-in panning lfo gives any puny, wimpy sound the width and depth that you only hear on the best mixes. Just imagine how it sounds when you send a fat, punchy signal through it! Definitely the most worthwhile purchase I have made in a while. The price to performance ratio is ridiculous.
Thanks for an incredible product.

Many thanks for the Z Filter. I just tried it out and it's a real gem. The free filters are fine but this is exactly what I've been looking for - high/band/low in one unit with its own distortion, LFO, ring mod' etc. It just sounds more 'real' than all the others I've tried so far. Lovely job.

Z Filter seems to always sound great, it reacts more smoothly than anything that can be done in the modular, &, most importantly, it's inspiring in a way that Pulsar rarely is. It's also hella fun.

I was never happy with any of freeware filters for Pulsar but now I can experiment many things with Z Filter and that makes me happy.

I just Tried the new Z Filter 1.1 and everything works great and I really like the new features. Is this Customer support or What!!

The Z Filter is just the best around no question, and I only just realised what you can do with env triggering which is so cool. We're using it to make great new dance records here in Ireland and we just had one in the charts using the Z-Filter and we're about to release another one so THANX PLANET Z!!!!

Congratulations on the filter, it is definitely the most wicked
filter I've used on the Pulsar so far.
