Waldorf Pulse 2 Arpeggiator Pattern

[synthmania67]

Hi,

I´m trying to build a panel only for the Pulse 2 Arpeggiator Pattern, because I want to control all 16 Steps via Cubase.

The manual of the sysex implementation shows me values which I do not understand. For the 16 Events i use a combo with all the necessary names. The sysex code I put in is "F0 3E 16 00 20 5a ls F7" for the first step and it works, but also the time event is set always to "25%". This should not happen. Therefor I want to use also a combo with the 4 possible values.
And also a button for switching on/off the glide per event.

I´ve marked the description at the end of this document.

Maybe someone can help me building the right SYSEX message for the combo I want to use.

Hi @synthmania67

You need to populate the top three bits with data, otherwise you are always sending 0 (25%) for the step duration and 0 for (Slide).

The coding is best done in lua.

With everything set to max, the value sent should be 0x78 or 120. 🤔

The solution is to combine the three bit packed values and bit shift them up to the appropriate bit position:
You can optionally use the bit library to do this e.g: ll = bit.lshift(jmax(0, ll),4),g0= bit.lshift(g0,6)

Of course I can't test this but it should be about right. See panel and code:

Waldorf Pulse 2 Arpeggiator Pattern_1_0.zip

send_arp_pattern_format = function(--[[ CtrlrComponent --]] comp --[[ MouseEvent --]], event)
    --0glltttt (7 bits of data) 8th bit never used for MIDI data

    local tttt = panel:getModulatorByName("Type of step"):getModulatorValue()
    local ll = panel:getModulatorByName("Length of step"):getModulatorValue()
    local g0 = panel:getModulatorByName("Step glide"):getModulatorValue()

    tttt = jmax(0, tttt) -- an unset combo = -1 so ensure lowest value = 0
    ll = jmax(0, ll) * 16 -- an unset combo = -1 // bit shift left by 4
    g0 = g0 * 64 -- bit shift left by 6
    local str = string.format("F0 3E 16 00 20 5A %.2X F7", tttt + ll + g0)
    panel:sendMidiMessageNow(CtrlrMidiMessage(str))
end

Hi John, I don´t know what to say now. You´re totaly genius, because your code does the trick. I´m looking for a solution since one week or maybe more.
Thank you very much indeed for your help and kind regards,
