Curation notes for MaxMSP/Jitter Progress

July 2, 2009 at 3:06 pm (MaxMSP/Jitter Progress)

These blog entries show how my ideas were realised and informed by MaxMSP/Jitter. After getting my computer stolen at the end of unit 2, I had a fair amount of ground to cover again (since I lost all my patches as reference). I tested my surround sound in Max, and although it was successful, Logic provided a much more dynamic and easily workable solution. After much consideration, the interactive element was reduced to a simple trigger. This was due in part to losing my computer and hence my time, but also because I felt that a simple interaction could still be meaningful and serve my idea better. (more details of this in my report)

Seat-Trigger Test

The trigger is working as planned, though I still need to work on the transitions times:

Final Patch update

July 2, 2009 at 11:17 am (MaxMSP/Jitter Progress)

I’ve been tidying up my final patch, working on both its presentation, as well as smoothing out the transitions – it now incorporate the onepole object (for high/low pass filters). The addition of filters allow for much smoother transitions between the Journey  & River states.

Managed to find a solution to quick on-off triggering. Now, there is a timelapse after the initial seat-trigger goes on, which prevents any further input (e.g. on or off) for a period of time:

Still need to think through other possibilites of triggering, so everything functions as intended.

The Final Patch

June 28, 2009 at 12:55 pm (MaxMSP/Jitter Progress)

I’ve been working on my final patch in Max. It’s almost complete, though I still have to think through certain interactions with the seat-trigger. If someone triggers the number pad on and off in quick succession (perhaps by re-adjusting their behind!), then there is a fade in/fade out overlap which disrupts the whole patch! I’ll have time to smooth this out though, just need to think through some ways of gating the journeys fade object if this quick on-off occurs…


I am structuring the piece so that when someone enters the space, they encounter the River. When they sit down the journeys in to the city begin, as the light present fades down. The short journey compositions endlessly link together until the person stands up, which returns them to the River once again as the light fades up.

Jitter + projection

June 18, 2009 at 9:05 pm (MaxMSP/Jitter Progress, Visualisations)

I built some Jitter patches to test in the room today. Initially I wanted to generate a colour and have it fade to black, then up again when it received an input. This would serve as a model for the seat trigger. I came up with a couple of working solutions with a different assortment of objects:


In the end, I found the easiest and most flexible solution was to hack an example patch, adapting it to my needs. After getting to grips with a few new objects I created the final patch, which allowed me to crossfade between 2 videos (one blue circle and my ear/window music video), as well as adjust hue, brightness, contrast and saturation:


I’m thinking of layering subtle moving imagery underneath my colour, to add texture and motion to the feel of the space. Previous experiments of projecting a still blue felt a bit static, as if the objects illuminated by the light were frozen in time – even with my compositions playing. In contrast, todays tests with moving image restored the sense of time and the space felt more inviting, which is what I want!

Max MSP and surround

June 18, 2009 at 8:46 pm (MaxMSP/Jitter Progress)

I’ve still got a fair amount of work to do with the surround sound set-up, but since the physical construction is well on it’s way, there will be plenty of time to do this. Well… not plenty, maybe just enough! Been testing various patches I’ve made within the room. This is a picture of a patch that uses the pan4s object, allowing easy panning possibilities for rotary motion.


In theory I might actually be able to do all my panning in Logic (6.1 surround), then export split surround files – e.g. one for each output, so 6 mono files. Will test this over the weekend.

USB seat trigger

Originally I intended to hack / make one of these:


But after a bit of research I think a much simpler / cheaper solution will be to incorporate this into a seat:

Picture 3

Max has ascii key objects easily adaptable to suit my needs. So, I’m happy, one less thing to worry about!

ABN, LBS & VBS combined

May 31, 2009 at 3:16 pm (MaxMSP/Jitter Progress)

I’ve been working on a new patch today:

At regular intervals it cross-fades between random sections of 3 compositions; Albert Bridge (North), London Bridge (South) and Vauxhall Bridge (South). I’m quite happy with the results and looking forward to pushing it further. Perhaps it could be improved by making the moments between transitions slightly longer and more unpredictable.

I quite like the idea of disrupting the chronology of my journeys and allowing each listener to experience their own route through London. I must balance this with my own compositional judgement of where the journeys link together and what the connotations of creating transitions between two specific places may be.

Getting reacquainted

May 30, 2009 at 9:45 pm (MaxMSP/Jitter Progress)

I made a simple patch today to get me thinking about ways to work with my audio in Max again, now that my room is confirmed.

It was a slow start since I no longer have any of my old patches as references, but I persevered and managed to achieve… something slightly useful at least!

Asides from memory refreshment, I didn’t have a particular aim for the patch other than wanting it to play a number of randomly selected samples from a larger batch, and do it (somewhat) seamlessly.

Though the seamlessness wasn’t quite achieved (partly due to the length of samples, as well as being left raw), it could easily be improved upon and adapted towards the final piece.
