Are you sure of that?

Did you try sending audio through it as well?
Is that audible?

#767

Audio in dosent work.

#768

Just tried again with audio and LFO from the Brute and Iā€™m positive : thereā€™s no audio going thru, only cv mod.

#769

Thanks for testing:
Thatā€™s quite brilliant actually!

#770

errrā€¦ I have an opposite experienceā€¦

Which TD-3 have you? I have the red one.
Quite soon weā€™ll realize the blue has a reverb instead of a distortionā€¦ :upside_down_face:

#772

I wish it were so, since Iā€™ve got not much with a303 through a ds-1.

(Btw: Iā€™ve got a blue one)

#773

Red one too. Two of them. Documentation:

Yes, and?

#775

Both you and the manual are wrong. (!)

The Filter in is not a CV in, itā€™s definitely and audio in. Also, the audio doesnā€™t replace the internal VCO, it adds to it (not ā€œinstead ofā€).

#776

I should add that, for me, the fact that the internal VCO is not silenced when thereā€™s audio at filter in makes this feature a bit useless.

#777

I read something about setting the vco switch between square and saw to silence it.

that would be greatā€¦ will try.

#779

@thomaso, youā€™re right !

Crappy pattern as example:

TD3 with Manis iteritas at filter in (fade in)

TD3 with only Manis Iteritas, TD3 VCO switch between sqr and saw

Well, I made a video : the filter in acts as both an audio in and mod in. When I tried earlier I didnā€™t know the TD-3 had to be playing note to let the audio go through.

Very odd behaviourā€¦ canā€™t reproduce it with my own lfo. Will have to investigate this tonight.

Are you using TS or TRS. Manual says TS. TRS wonā€™t werk.

#783

TS, standard cable I use from my A-145

I use a TRS. Thatā€™s a cheap hack :upside_down_face:

#785

Upon further testsā€¦ I can confirm the filter in is an audio in. However, the filter has a different response given the sound source gain (be it internal or external). When a control rate signal (LFO, enveloppe) is applied at filter in it is added to the internal VCO and changes itā€™s gain, which effectively modulates the filter frequency. This is certainly not a clean CV input, but now I can see how it can be abused as a it.
