This is a really well designed synth....

Everything is laid out on one page so it's easy to drive once you get familiar with the setup...

There are lots of modulation options that bring a range of dynamics into play and help to give real character to the voices and the ability to load your own wavetables is a powerful feature...

One of the things I like about Bjorn's synths is that they have a slightly "raw" sound and this is a positive thing when it comes to the mix...

I got lost for a few hours playing with WhispAir and then used it in a track and it was all good...

Tightly coded with a small install size, a powerful sound and a resizable GUI, what's not to like ?

Thanks Bjorn....this one's a winner....

I like WhispAir a lot. I am biased on the GUI because my first synth was a KORG. Anyway, to me it is the most user friendly wavetable synth I have come across (boomer). Also, SYNC, FM, AM, and FM X-MOD are all available. Down at the bottom you will see a very good implementation of unison if needed. It's all on the front panel, KORG style, but there is a lot here. I will be spending many hours making sounds with this. You can set the start phase of the oscillators, something no KORG could do. Wavetable import works well. You can also import SSWs. I think KORG should render this in hardware.

I played yesterday with WhispAir, and it is a very capable synth, mainly because all functions are on screen. So it is very intuitive and straightforward, recommended for a newcomer to wavetable synthesis. Although it ships with a limited number of wavetables, the ability to load custom ones takes it to the next level, almost in par with Pro synths (or even better, as f.ex. some commercial wavetable synths do not import custom wavetables). To my impression, the synth could have benefitted significantly by the existence of a second filter and/or a richer collection of filters (e.g. notch), but I understand that the developer aimed to keep things simple, closely resembling to what a hardware wavetable synth of $300-$400 would have offered. In general, WhispAir is a very decent synth, covering an area which had no similar ones (that of a hands-on wavetable synth, without blows and whistles), from the user perspective seen as kind of a hybrid between Odin2 and Vital, keeping good features from each of them, thus addressing the new user (who would likely opt for a freebie, but wouldn't feel comfortable with all the details in Vital, but looking for more than what Odin2 offers), while being much easier to learn (and focused for that reason) than equivalent commercial ones. The chorus fx that it comes with is very powerful, and in my testing I tried the synth with my preferred delay and reverb inserts, which complete, to my taste, adding character to the synth patches. An EQ before the rest effects was also added, which is another feature I'd like to see as a built-in fx in this synth, in a future version (the first feature being a bigger filter section). Overall, I would like to see it going well in the competition of the KVR, so as the developer gets compensated for their effort on this great synth idea. For me, it is a quick-and-easy sound setup synth, so it is definitely a keeper.

"Blofeld Wavetable Creator" wavetable output (.syx) is readable by WhispAir. http://lady.rdsor.ro/~kotro/index.php?m=soft#blofeldwavetable

I download 40 Blofeld Facebook syx wavetables, but how do I install? The files are syx, but WhispAir only recognise .fxb. I tried to rename it, but it didn't work. Any tip?
