Barely a synth sound

> here’s the first video with the drummachine. If i’m correct and doing what the manual says… the bandwith knob should be knob 10 right? but it’s knob 9 or am i really that blind?

It looks like there are shorted pins on the 4051, or maybe bent pins when you inserted the chip in the socket. The wiper of pot 9 should be continuous with pin 1 of IC18. The wiper of pot 10 should be continuous between pin 2 of IC18. If you have a short between both pins when the two pots are in middle position, there’s something wrong somewhere…

> and here’s the video about the ADSR. Notice that the midi note stops, but the sound of the synth won’t ‘release’. Don’t know if this is normal for the anushri but if it is then i really ask myself why it has a release button.

The amount of ADSR envelope applied to the VCA is adjustable by the knob at the right of the release knob. In your video, this knob is clearly set to 0, so the ADSR knobs has no effect on the VCA, only on the VCF. But it might be due to the problem above with pot 9’s signal overriding pot 10.

Also, the case looks much better without the protective packaging :slight_smile:

First, it would be a great idea to remove the protective Foil from the Plexi - as long as you arent a fan of the Evonik Design.

Second you should reread the section about the Envelopes. It could be that your VCA ENV Pot is set totally to the right (although the physical position is to the left) so the VCA Env which makes for your ‘release’ is totally solidified and the VCA Envelope has a rather Gated shape with no release. So turn Pot 10 CW and hear yourselves.

This behavior of the Pots is fully intended (as you can read in the Manual) as it would be a catastrophic thing all settings would snap to the actual Pot settings when changing the Menus in a live situation.

For the PW its the normal behavior, if your Pulsewitdh is 100% (FULL CW) then the pulse takes 100% of the cycle which means its 100% on - you cant hear anything because the signal never leaves the +5V level.

What you are hearing when tweaking Knob 9 is the HiHat tone changing (again, as described in the Manual) and only the HH - the other sounds are not affected as far as i can hear it on the iDevice speaker. Since the HiHat is a sample (read Manual) its altered by the Readout frequency and with this the Bandwith of the HiHat sound changes.

Its clearly different from what Knob 10 does, this Bitcrushes all sounds simultanoeusly.

So its not your Unit behaving wrong, its you having different expectations of what happens.

@fcd72: I think there’s really a problem, what I hear when pot 9 is tweaked is the bitcrushing, not the HH transposition.

@pichenettes: OK, ill try find some earplugs…

haha darn! didn’t had a clue it was protection packaging :smiley:

@pichenettes -

maybe the video didn’t demo’d it good, but when i use the VCA knob it doesn’t do anything really to the ADSR. At least not with the release. Should i reconsider to solder the ic of 4051 to see if it works?

@ fcd72 -

The ADSR isn’t really working as i suspected i think. I thought the synth could get a tail when you have the proper settings, but whatever i try with the VCA knob and release knob, it won’t a get a nice tail when the midi note stops.

as for the drums and bandwith knob. Maybe you don’t hear it properly in the video, but button 9 does the bitcrushing on ALL the drums… instead of knobs 10 that doesn’t has a function in the drums section right now.

Both problems are consistent with signals on pot 9 and pot 10 interfering with each other, or one overriding the other. Check the 4051.

Having found some Headphones i second pichenettes. I think pot 9 does pot 10s job and pot 10 does nothing. You seem to have a some connection problem as pichenettes pointed out. Check everything around the pot9, 10, the 4051 and if there is mistakenly some debris in the board to board connections.

Hey guys!

Good news :-)!
I resoldered IC 18 and IC 17 just to be sure and it works like a charm right now!

Thanks a lot for your patience, time and help. I can enjoy my Anushri now to the fullest.

can’t tell you how much i appreciate it :-)!

Also take a close look at the soldering of the connectors between the boards. Maybe you have short there.

Congrats! (That’s twice in this thread, crossing with another post…)

hahaha true that! sorry for the hassle guys. I’m already lost in the AnushriSphere!
