Late Burns Night and St Patrick’s Day

Leave a comment

We had a delayed Burns night, seems a bit of a habit of our band.
But with Covid, who knows, maybe we are celebrating Burns Night 2020.

I wanted to make Haggis “bitterballen” (Fried balls) but Irmgard has no frying pan. So I made some Haggis sausage rolls.

The others made also a lot of Scottish/Irish themed food. (Too much again) But i don’t have the recipes.

We played some old tunes, and some new. Talking eating and drinking, time flies!

Irmgard and I played a duet on the Harp and some new tunes on the Concertina.

Wellll the recipes:

I wanted to make this one:
https://cookingwithbry.com/haggis-bon-bons-recipe/

Instead I made this:

  • 392g haggis, canned haggis ( Holiday 2022, stuffed a load of cans in our car )
  • 3 Sausages (that is about 200 gr)
  • Bunch fresh parsley, finely chopped
  • 320g ready rolled all-butter puff pastry
  • 2 tbsp Dijon mustard
  • 1 free-range egg, beaten

Mix haggis, sausagemeat and parsley.

I used square “bladerdeeg” for pastry, made a roll out of one square filled with the haggis. (Takes about of 13 sheets).
Brushed on the beaten egg, and put on baking paper.
20 Minutes in a 180 degrees oven.
Cut up each roll in 3-4 parts.

Eleanor Plunkett for Harp

History about this tune:

Arranging this tune for a duet. (Imgard and myself)

This is a work in progress

I’m using Musescore for this typesetting

Eleanor-v0.5

A Nelly an chuil chraobhaigh
Is a shuil ar dhaith an fheir ghlais
Ag eirghe dhon la,
O! nach breag dham so a radh,
’S gur [tu] do shliocht na bhfear eifeacht
O Ardmacha breige,
Fuair sar-chlu o Ghaodhalaidh
Le trean-neart a lamh.

O Nelly of the back of the wood
With her eye the color of the green grass
Waking with the day,
O what a lie it is of me to say,
And you with your family from a man of import (?)
O lying Ard Macha,
(Nelly? The man? Ard Macha?) Won great fame from relations
With strength of hand

Wanted to make a mini Sid Player, and failed

Leave a comment

I’ve got an old Speaker Phat, and a Raspberry Zero

An audio add-on board for Raspberry ( same size as the Zero )
Connections

My initial idea was to have the “High Voltage Sid Collection” (Downloaded the 55000 pack)
On a mini device, battery operated and with a little keypad.

On the keypad i can select the Sidtune to play, or pressing
A and a number the Sids from a certain artist.

The display gives you information about the tune being played.
( The display has an I2C hat to convert 8bits to I2C )

See pinout phat above.
I’ve got three choices for I2C connection (green/blue to the Phat)

  • Direct connect and use different addresses
  • Use a I2C hub and different addresses
  • Define a secondary I2C on the raspberry

So I made the first test setup …

Underrun occurred .. So back to the drawingboard.
I probably need a better Audio Hat.
First to try .. Zero fast enough for sidplay2?
Maybe audio over hdmi works??

A Harp in the house again. JOY!

Leave a comment
Temporarily a Harp to take care of.

First I have to replace 4 strings.

Apparently F4 B4 F3 and D1

I’ve replaced strings before so that’s no problem. Starting all over again.

Our Folk Band Harp player wants to due some duets. So lets get playin’

http://pinnerstringquartet.com/

UPDATE: 20230119
Replaced the 4 strings yesterday, not fully tuned yet.
Gave the string some time to rest.
Looking at the harp this morning. G4 was broken .. d*mn

UPDATE: 20230126
Replaced also the G4, all done.
Tuning this kind of Harp. (Salvi Lever harp)
You have to put all levers down, and tune them from lowest note to highest.
The A B and E strings have to be tuned flat!
So by using the levers you can play in all kinds of different keys.

VGA .. first card also machine code hacking
Matrox
Some cards i knew a lot about, i did some manipulations using assembly that were very interesting, but only worked on that specific brand.

16 Bit ISA VGA card that is compatibe with 8bits slots for my XT.

Sound:

I’ve bought a lot of Crystal Soundcards, there were breeze to install and use under linux, way back when it was hard to get supported hardware.



Firewire card (for Studio equipment):

Our old trusty mixer

Videocapture:

Video blaster – Which i used to record video (Like ‘Sepp en fash vervelen zich nooit’) and my DIY controllable webcam.

Catweasel

The Catweasel is a family of enhanced floppy-disk controllers from German company Individual Computers. These controllers are designed to allow more recent computers, such as PCs, to access a wide variety of older or non-native disk formats using standard floppy drives.

You could connect joysticks and there is a socket for a SID chip on the card.

ABC to Animation for Concertina

Leave a comment

I want to take simple ABC Music notation tunes and convert these to animations which shows you which keys to press and to push or pull.

This is a work in progress.
Script is using ImageMagick and ffmpeg

I started this in bash, and i should rewrite this in python.

Bash script which generates the images

#!/bin/bash
convert -size 800x600 canvas:white white.png
x=55
y=55
draw=""
for xx in $(seq 1 6); do
for yy in $(seq 1 5); do
	startx=$(( $x * $xx + 100))
	starty=$(( $y * $yy + 200))
if [ $xx -gt 3 ] ; then startx=$(($startx + 200)) ;fi
draw="$draw  -draw \"circle $startx,$starty $(( $startx - 10)),$(( $starty - 10 ))\""
done
done
echo convert $draw white.png          draw_circle.png | bash

for xx in $(seq 1 6); do
for yy in $(seq 1 5); do
        startx=$(( $x * $xx + 100))
        starty=$(( $y * $yy + 200))
if [ $xx -gt 3 ] ; then startx=$(($startx + 200)) ;fi
convert -fill white -stroke black $draw  -draw "circle $startx,$starty $(( $startx - 10)),$(( $starty - 10 ))" draw_circle.png $xx-$yy.png
convert  -draw "rectangle 300,50 500,100"  $xx-$yy.png push-$xx-$yy.png
convert  -draw "rectangle 150,50 650,100"  $xx-$yy.png pull-$xx-$yy.png
done
done

Example movie generated using random notes/length pause 

for f in $(seq 1 50) ; do
pushpull=$(shuf -n1 -e push pull)
row=$(shuf -n1 -e 1 2 2 2 2 2 3 4 4 5 5 5 6)
col=$(shuf -n1 -e 1 1 1 2 2 3)
pauze=$(shuf -n1 -e 0 0 0 0 0 0 0 0 1 )
length=$(shuf -n1 -e 1 1 1 1 2 2 3 4)
file="$pushpull-$row-$col.png"
if [ $pauze == "1" ]; then
file="draw_circle.png"
fi
for f in $(seq 1 $lenght) ; do
echo "file $file"
echo "duration 0.5"
done
done

list to mp4

ffmpeg -f concat -i list  -vf fps=10 -pix_fmt yuv420p test.mp4

Above movie shows left and right hand. Keys to press.
And the bar above represents PULL/PUSH

Todo/In progress:

  • abc parser ( started )
  • Push/Pull as text in above movie also note to play??
  • Rewrite to python

Bella Ciao on Concertina

Leave a comment

In post below i posted the score for Bella Ciao
https://www.henriaanstoot.nl/2022/12/09/generating-pdfs-from-abc-files-to-include-in-tunebooks/

Here is a quick ‘n dirty recording (sound a little distorted)

Edited with Kdenlive

I’ve imported the score as an image.
Drag a transform effect on the image.
Move the image to the bottom of the screen.
Add a keyframe.
Move to the end of the movie, add another keyframe.
Adjust the Y position to 0
Set opacity to a nice position and render
