Really excited as well! Got a pair on the first run and am looking forward to working with more.

That would be really cool if there could be a waiting list for those who missed out on the last run honestly.

I do hope you get a couple of Telex this go round @madeinspace and would hope that @bpcmusic put you on a priority as you were so close last time. I bought two TXoā€™s and one TXi that day and now with the i2c connection to my ER-301 I feel well setup with my Monome system so far. Now I need a Grid and Iā€™m certain Iā€™ll be wanting the New Thing! whatever it may beā€¦oh and the Faderbank :slight_smile:

Thanks yeah really hope I can make it this time. Is there a new monome thing coming up? :smiley:

noticed this morning that the envelopes coming out of my TXo seem to dip below 0v at the end of decay. i was using it with a filter and could hear it happening so i ran i through the scope on er-301 to see what was going on and sure enough, there is a brief dip. i have attack set to zero, the decay set to 1000 and the voltage is controlled by a TXi knob. Is there something really obvious that would cause this? i donā€™t use TXo for envelopes very often so i mightā€™ve missed somethingā€¦

Thanks for reporting. Can we get a little more info?

  • What is your resting voltage at TO.CV 1 0? Have you calibrated it?
  • What do you have your envelopeā€™s peak voltage set to?
  • What firmware version are you running on the TXo?
  • How far below zero are you seeing the dip?

That will help us replicate/evaluate what you are seeing.

Iā€™m excited to understand and (potentially) catch a bug! :slight_smile:

Is that weird?

Haha, not weird, means your a real dev :wink:

Up until now Iā€™ve been using TT input 1 for clock duties regarding Telex TXo trigger duties. Tonight I was trying to find how I could use input 2 or 3 or 4 etc., to drive TR 2, 3, or 4 independently of the clock in TT input 1?

880

What exactly are you trying to do? The question isnā€™t totally clear. Thx!

881

I have a clock signal going into jack #1 on the Teletype.

The TXo SC.TR #1 is sending out a trigger to the ER-301 using the clock signal from the Teletype.

I want to use a clock division on SC.TR #2 for a trigger to another unit on the ER-301, so my idea was to patch another clock signal in jack #2 on the Teletype. As Iā€™m typing this out Iā€™m starting to feel that Iā€™m missing something regarding using a math operator on the SC.TR command line???

882

Are you using the Teletype SC ops to directly control the 301? If so, that doesnā€™t involve the TXo at all.

Iā€™m also still having trouble following what youā€™re trying to achieve. Could you share your TT code?

If you want a division of the clock coming in from Input 1 then you should be able to do that in the script, and then send the new divided clock to any output you like.

If you want a completely separate clock then you could use a separate input, in your script you would read from the new input instead of Input 1 to get the new clockā€¦

I feel like Iā€™m still not really understanding

883

Huge blunder in thinking on my part as to why was I thinking the TXo had any role.

What would the syntax be to divide the clock signal per output when using SC.TR as Iā€™ve never defined the clock source?

Again regarding the SC.TR operator, how do I specify a specific input?

884

Youā€™ll probably get better responses to SC specific questions over on the O|D thread.

You need an event to trigger that. I would put these scripts into M and create rules to trigger them (using the EVERY command, I believe). You can also put these into a numbered script, but that script needs to be triggered by a clock source.

Also, yeah it doesnā€™t sound like the Telex expander is what you want if you donā€™t want to physically patch into the ER-301.

886

I think Iā€™ve just spotted my break in logicā€¦because I have 100 possible triggers or cvā€™s to the ER-301 I was failing to associate a script number to an input number ā€“ oops.

What I was trying to do was along these lines:

#1

SC.TR 1
SC.TR 2 : assign a different clock division

instead of:

#1

SC.TR 1

#2

SC.TR 2

It all seems so obvious now, but late at night when I first asked the question I should have tried sleep instead :slight_smile:

I also think I thought about addressing this in the Telex thread due to Brendon being key in this merger between Monome and O|D.

I would do the clock division within the ER-301 and use just one SC.TR from teletype. Seems easier to me and does not use another teletype script.

Maybe we create a thread here to talk about the i2c integration with the ER-301, link to the appropriate pages over at the OD site/forum, and have any ER-specific scripting discussions? If that sounds like a good idea, I can prime the thread in a little bit. :slight_smile:

Hi ā€“

Longtime lines reader first time posterā€¦

Iā€™m planning on DIY-ing a TXi and TXo and was a little bit unsure about the exact header requirements for each -

If I have a few rows of 1x40 machined pin headers (male) and a few machined female for the teensies, a few rows of 1x40 standard 2.54mm (male + female - for connecting the boards), and a 2x40 standard 2.54mm (male - for power and maybe i2c), should I be good? I think I need to get something separate for the POGO 2x3 i2c connection but couldnā€™t figure out exactly where to get that or what pogo meantā€¦

It wasnā€™t clear to me exactly what the device names on the BOMs were specifyingā€¦

Silly question but a little guidance would be appreciated!
