Fathom Synth Development Thread

[RPH]

SM, RPH, You may also notice that when you move the modulation amount now the minimum and maximum values of the modulation range are now displayed on the target dial.

Yes indeed, works great as well!
Makes it a lot easier to set the values I want.

Cheers!

- Panning of Noise only works when the voices switch is set to detune, could you make it that mono also allows panning?
- LFO period doesn't show min and max mod. range.

[FathomSynth]

OK, I just fixed the Period dial so it shows the modulation range.

Yes, you're right, the Noise should follow the oscillator's pan dial even if it is in mono mode. I'll fix that in 2.4.

For 2.5 when I do the oscillator redesign, the Noise will probably have its own separate Pan and/or Stereo Width dial.

Thanks!

Today I sampled 16 single cycle waveforms from my Yamaha DB50XG.

- How do I save the table with the name I want?
I named my table at two locations but when I press save it becomes Wavetable 1, 2, 3, etc.
The manual doesn't describe it.



- Possible issue, could reproduce it several times..until I recorded it..
When I loaded my created wavetable and used the mousewheel to move thru the index, it kept showing the first wave ( only shows the others at the very first second while switching ).

PS:
At some point a dedicated sampleplayer in Fathom would be great, single cycle waves lack the tru sound I hear in my synth.
Was thinking about a dual sampleplayer, with the same morphing options as with the wavetable component.

What I have found to work is allow Fathom to save it as wavetable 1, then highlite the word wave 1 in the browser and rename it. No need to re save. It keeps it and can be recalled later.

Feature reguest..

Comb filter.

Yeah, I did that as well but should not be the way to do it imo.
Naming a wavetable should be as easy as naming a preset, not afterwards in the browser.

Another featurerequest:
- Copy a modulator.
- Wavetable component: Save a morphed waveform ( middle window ) to disk. Got a really good sounding one today I wish I could save as a new waveform.

[FathomSynth]

OK, Some good ideas here: I put these in the priority feature list.

Noise should follow oscillator pan dial for both mono and detune mode.

Be able to set the name of a saved wave table using the middle title bar, also the middle title bar should show the name of the wave table while scrolling through them in browser.

Wave Table Sampler like Wave Table oscillator but with Sampler oscillator objects in each position instead of the individual waves.

Comb Filter.
Copy Modulator Button (Also save and load modulators).
Wave Tabel save Middle Wave state as a separate waveform.

Yes, SM is right, for now the only way to name a wave table is to type in the name in the Browser row, and it will remember it, but I admit that is sort of confusing.

SM, you might try the Polar Morph filter, it has a Comb Filter option. I'm not sure how will it would perform for a modulated cutoff but it's worth a try, and yes I will add a Comb Filter. There will also be a new Zero Delay Filter in the next release.

Thats funny, somehow I figured a comb filter was hiding in one of the more obscure filters as soon as i posted the request.

I have been doing some SD research lately and have discovered some cool uses for a comb filter. I didnt recsll seeing one but it has been quite awhile since I clicked on the polar morph filter. I will check it out tonight. Maybe Fathom already has this too.

[FathomSynth]

Actually now that I think of it, a better option would be Band Stop filter with a high resonance value, that way you can modulate the frequency with one dial.

I'm not real familiar with comb filters, if you want multiple comb points modulating you would have to put two or three Band Stop filters in series.

A comb filter is really just a slightly delayed version of the original signal mixed back in with the original. Because of the slight delay the two waves become slightly out of phase. This causes peaks and valleys at equal intervals across the spectrum. This effect allows you to simulate physical bodies such as a cylinder or string motion. Some very realistic physical modelling can be achieved. Being able to simply control the delay time, intensity and feed back would allow for most uses.

I know you want to add a simple delay in the future. It maybe able to serve this function as well. The existing delay can probably do it but we don't have access to the parameters for modulation.

here is a link to one example of implementation

There is also Triple Cheese a freeware synth that is simply three comb filters. Its a strange beast but it gives you a good idea of how that concept sounds by it self. Of course Fathom has all of the other types of synthesis that you could combine with for further depth.

I uploaded a new video today.

This one explores some more wave table possibilities. Be sure to check the description for down load links to get the wave files and tables used in some of the examples.

When I originally loaded the SQ80 waves into Fathom I had to convert the AIFF waves to WAV. Since Fathom is now OSX compatible does it load AIFF now?

[FathomSynth]

SM, Thanks for the video, and covering the Wave Table was a great choice.

Thanks for the info on the Comb filter, I'll add that to the list, and try to get it in at some point.

The oscillator redesign is planned next, since the number one feature request by most people over the last couple months has been to get the partials up to the Nyquist and fix the CPU bump when notes go high, both of which are easily fixable with a little redesign. I also have an idea for getting rid of the dial stutter completely.

But good news for this release, I will be adding a copy modulator button, actually starting that right now. 2.4 will be out this week for sure. Should also fix the last of the validation issues.

Sweet, think many will be very happy with that update!

Here is a link to a corrected version of the video I posted a day or so ago. I have also edited the above post to reflect the new version.

The previous version froze up around the 8 min mark.
